- This script should be used when requesting the correct time from an ntp
- server (time server). If an ntp server is queried, it updates the system
- time. This script saves this updated time to the battery clock of the Amiga
- and optionally creates a logfile to keep track of the correction applied to
- the system time.
-
- To get an address from an adequate ntp server, have a look at
- 'http://www.cis.udel.edu/~mills/ntp/servers.html'. Choose one and insert
- the address into the relevant string gadget (bottom of 'TCP/IP' page).
- Don't forget to activate the 'Get Time' switch.
-
- Then enter the path/name of this script (e.g. ARexx/savetime.miami) into
- the 'Online' string gadget ('Events' page). This starts the script as soon
- as the ntp server transmitted the time information.
-
- Optionally, the corrections applied to the current system time can be
- logged to a file. If this is desired, set the 'log' variable to 'true'
- (default is 'true') and enter the path/name of the log file (default is
- 'Miami_Time.log').
-
- Example of a log file:
-
- Date old time ntp time error

- The variable 'secdelta' takes system speed into account and has to be set
- accordingly. Fast systems use 1 (68060), slow system 2 or 3 (68020). To
- find the correct value, run the script a couple of times with the log
- option enabled and analyse the log file. The average of the time errors is
- the value to enter here (in seconds).
-
- ENVARC:TZ must be set up correctly as well. Have a look at 'http://www.ifh.
- de/computing/manuals/infohtml/glibc/library_318.html' for details. For
- Luxembourg, I have "CET-1". For some reason, "CET-1CEST-2" doesn't work
- properly on the Amiga. Therefore, I change TZ manually to "CET-2" for
- daylight saving. Apparently, TZ only accepts 3 digits as national time zone
- code. In fact, the 3 digits aren't used, which means that "xxx-1" or
- "xxx-2" would work as well.
-
- The file "tzdata1997a.tar.gz" gives even more detailed information. It can
- be found at "ftp://elsie.nci.nih.gov/pub". Here the most important zones.
