ΓòÉΓòÉΓòÉ 1. What is TimeKeeper/2? ΓòÉΓòÉΓòÉ
TimeKeeper/2 retrieves Coordinated Universal Time (UTC) from a time server
using time protocol RFC868. and compares the results to your system time and
optionally updates your system time if necessary.
TimeKeeper/2 can be configured to adjust for Daylight Saving Time if you
provide your time zone information in the program settings.
TimeKeeper/2 has a set of predefined NIST (National Institute of Standards and
Technology) servers which are synchronized with an atomic clock. When
TimeKeeper/2 is installed, a server is automatically selected for you and may
be changed at any time if you wish to use a different predefined server. If you
have a preferred time server that is not in the preconfigured list there is an
option to add servers.
TimeKeeper/2 is as accurate as possible. Due to network delays and the 1
second time resolution of the time protocol you may encounter situations where
the Local Time and Server Time are off by 1 second. This is normal and
unpreventable.
If you have any questions please contact us .

Server Time Display
Status Line
The Query and Adjust Buttons
ΓòÉΓòÉΓòÉ 2.1. Menu Bar ΓòÉΓòÉΓòÉ
The Menu bar consists of two items:
TimeKeeper/2
Help
Through the TimeKeeper/2 menu you can access
Settings dialog,
Registration dialog,
or exit TimeKeeper/2.
ΓòÉΓòÉΓòÉ 2.2. Local Time Display ΓòÉΓòÉΓòÉ
Local Time displays your current system clock settings.
ΓòÉΓòÉΓòÉ 2.3. Server Time Display ΓòÉΓòÉΓòÉ
Server Time displays the actual time on the NIST time server.
If the server has not been checked or is unavailable the display will let you
know that the server is not accessible. You may wait a moment and try again or
select another server.
ΓòÉΓòÉΓòÉ 2.4. Status Line ΓòÉΓòÉΓòÉ
The status line contains information about current operations and the
difference between your system time and server time.
ΓòÉΓòÉΓòÉ 2.5. Query and Adjust Buttons ΓòÉΓòÉΓòÉ
The Query button queries time from the server.
The Adjust button changes your system clock to match the server time.
ΓòÉΓòÉΓòÉ 3. Settings ΓòÉΓòÉΓòÉ
The TimeKeeper/2 settings allow you to configure the various functions of the
program.
All the settings are divided into 3 groups:
Options
Time Zone
Servers
ΓòÉΓòÉΓòÉ 3.1. Options ΓòÉΓòÉΓòÉ
Auto Check Time At Startup
TimeKeeper/2 will automatically query the time from a server when the
program is started.
Auto Adjust Local Time
TimeKeeper/2 will automatically adjust local time when the local time does
not match the time received from the time server.
Start minimized
TimeKeeper/2 will start minimized.
Tip: TimeKeeper/2 is ideal for your startup folder when started minimized
with options
Auto Check Time At Startup,
Auto Adjust Local Time,
Query Time from Server(s) Every: N minutes
enabled.
Minimize to Clock Bar
TimeKeeper/2, when minimized, will display current local time, the time
difference between local and server time and network activity in a small
window ( Clock Bar ).
12 Hour Time Format
Time will be displayed in 12 hour format (AM & PM).
Server Time in the same TZ as Local
Server Time will be modified to use your time zone settings if you provide
your time zone information.
Clock Bar Float On Top
The Clock Bar will be always on top.
Time/Date Presentation
Time only
Date will not be displayed.
Date and Time (Digital)
Date and Time will be displayed as digits.
Date and Time
Month will be displayed as words.
Query Time from Server(s) Every:
If this box is checked TimeKeeper/2 will query the time server on a
regular schedule (in minutes) as specified in the entry field next to the
checkbox.
ΓòÉΓòÉΓòÉ 3.2. Time Zone ΓòÉΓòÉΓòÉ
Time Zone information is required if you want TimeKeeper/2 to automatically
handle local time.
For more information see:
Do not Use Time Zone Information
Use TZ Environment Variable
Use the Following Time Zone Information
ΓòÉΓòÉΓòÉ 3.2.1. Do not Use Time Zone Information ΓòÉΓòÉΓòÉ
With this option enabled TimeKeeper/2 will not use time zone information.
TimeKeeper/2 will be able to keep your system matched with the server time but
it will not be able to automatically set Daylight Saving Time.
TimeKeeper/2 will ignore any difference between local and server time if the
difference is equal to a certain number of hours. For example, if the local
time is 10h:30m:00s and the server time is 11h:31m:03s, TimeKeeper/2 will
report the difference as 1m:03s. If the server time was 11h:29m:03s,
TimeKeeper/2 would report the difference as -57s.
ΓòÉΓòÉΓòÉ 3.2.2. Use TZ Environment Variable ΓòÉΓòÉΓòÉ
This option forces TimeKeeper/2 to use the TZ Environment Variable
This is useful when the variable is set by another program or is configured in
your config.sys file using a SET statement.
ΓòÉΓòÉΓòÉ 3.2.3. Use the Following Time Zone Information ΓòÉΓòÉΓòÉ
With this option you may select one of the provided time zones or set the time
zone manually.
For more information about setting the custom time zone information see TZ
Environment Variable. You can edit the 'Resulting TimeZone' string
Note: Do not enter "SET TZ=", this is unnecessary.
ΓòÉΓòÉΓòÉ 3.2.4. TZ Environment Variable ΓòÉΓòÉΓòÉ
This is an excerpt from the C Runtime documentation which describes the TZ
Environment Variable.
This variable is used to describe the time zone information that the locale
will use. To set TZ, use the SET which has the following format:

For example:
SET TZ=CST6CDT
sets the standard time zone to CST, the daylight saving time zone to CDT, and
sets a difference of 6 hours between CST and CUT. It does not set any values
for the start and end date of daylight saving time or the time shifted.
When TZ is not present, the default is EST5EDT, the "C" locale value. When only
the standard time zone is specified, the default value of n (difference in
hours from GMT) is 0 instead of 5.
If you give values for any of sm, sw, sd, st, em, ew, ed, et, or shift, you
must give values for all of them. the entire statement is considered not valid,
and the time zone information is not changed.
ΓòÉΓòÉΓòÉ 3.3. Servers ΓòÉΓòÉΓòÉ
This page allows you to select the time servers which will be queried for time
and specify the protocol used by these servers.
Servers Available
This is a list of predefined NIST servers.
Servers Available ( user's )
This is the list of servers which were added by the user. Press the 'Add'
button to add a server and 'Delete' button to delete a server from this
list.
Servers Selected
This is the list of servers which will be queried for time. You may have
more than one server selected and TimeKeeper/2 will then cycle through the
selected list. For faster results select a single server rather than
multiple servers.
To insert a server into the list, select the server in one of the Servers
Available lists and press the 'Insert' button. The 'Remove' button removes the
server from the list.
Protocol
Time protocol may be used either above the Transmission Control Protocol (TCP)
or above the User Datagram Protocol (UDP).
For most cases TCP protocol is accepted by a server. The TCP protocol also
provides better accuracy when network connection is slow.
If a time server does not respond to TCP requests try to use UDP.

ΓòÉΓòÉΓòÉ 6. RFC878 ΓòÉΓòÉΓòÉ

Time Protocol
This RFC specifies a standard for the ARPA Internet community. Hosts on
the ARPA Internet that choose to implement a Time Protocol are expected
to adopt and implement this standard.
This protocol provides a site-independent, machine readable date and
time. The Time service sends back to the originating source the time in
seconds since midnight on January first 1900.
One motivation arises from the fact that not all systems have a
date/time clock, and all are subject to occasional human or machine
error. The use of time-servers makes it possible to quickly confirm or
correct a system's idea of the time, by making a brief poll of several
independent sites on the network.
This protocol may be used either above the Transmission Control Protocol
(TCP) or above the User Datagram Protocol (UDP).
When used via TCP the time service works as follows:
S: Listen on port 37 (45 octal).
U: Connect to port 37.
S: Send the time as a 32 bit binary number.
U: Receive the time.
U: Close the connection.
S: Close the connection.
The server listens for a connection on port 37. When the connection
is established, the server returns a 32-bit time value and closes the
connection. If the server is unable to determine the time at its
site, it should either refuse the connection or close it without
sending anything.
When used via UDP the time service works as follows:
S: Listen on port 37 (45 octal).
U: Send an empty datagram to port 37.
S: Receive the empty datagram.
S: Send a datagram containing the time as a 32 bit binary number.
U: Receive the time datagram.
The server listens for a datagram on port 37. When a datagram
arrives, the server returns a datagram containing the 32-bit time
value. If the server is unable to determine the time at its site, it
should discard the arriving datagram and make no reply.
The Time
The time is the number of seconds since 00:00 (midnight) 1 January 1900
GMT, such that the time 1 is 12:00:01 am on 1 January 1900 GMT; this
base will serve until the year 2036.
For example:
the time 2,208,988,800 corresponds to 00:00 1 Jan 1970 GMT,
2,398,291,200 corresponds to 00:00 1 Jan 1976 GMT,
2,524,521,600 corresponds to 00:00 1 Jan 1980 GMT,
2,629,584,000 corresponds to 00:00 1 May 1983 GMT,
and -1,297,728,000 corresponds to 00:00 17 Nov 1858 GMT.
ΓòÉΓòÉΓòÉ 7. The TimeKeeper/2 Clock Bar ΓòÉΓòÉΓòÉ
TimeKeeper/2 can be minimized to Clock Bar when option Minimize to Clock Bar is
checked.
TimeKeeper/2 Clock Bar consists of three fields:
Local Time
displays current local time.
The Time Difference
displays the difference between local time and server time. If server time
was not queried the field displays -.
Network Indicator
the indicator displays if server time is being queried.
ΓòÉΓòÉΓòÉ 8. The TimeKeeper/2 Command Line Options ΓòÉΓòÉΓòÉ
TimeKeeper/2 has the following command line options:
-adjust
TimeKeeper/2 starts, connects to the time server, adjusts local time and
quits. Return code ( errorlevel ) is equal to 0 if the time was
successfully adjusted.
ΓòÉΓòÉΓòÉ 8.1. Add New Time Server ΓòÉΓòÉΓòÉ
This dialog allows to enter information for a new time server.
It contains the following fields:
Name
An arbitrary name for the server. The server will be referred to by the
name.
Address
Internet address of the server ( fully qualified domain name or decimal IP
).
