DateTime point accesses the calendar functions on the Pocket PC, and can record current and other times. (This point function is not available on the desktop PC.)
On-screen, DateTime points appear as a caption followed by a check box and date and/or time string. Tapping the check box will record the current time and/or date; arrow controls enable alteration to date and times, either by launching a calendar or first selecting the value and using arrows to make changes.
A number of date and time formats are available, including YYYY-MM-DD, DD-MM-YYYY and MM-DD-YYYY, and 24-hour time with and without seconds.
Maths
If a DateTime point is included in a Math point's expression, the time and/or date will first be converted into a number. Where a date is included, this number will be the number of minutes since January 1st, 1979. If there is only a time, the number will be the number of minutes since midnight. If the DateTime point includes seconds, they appear as a decimal portion of a minute (30 seconds is 0.5 minutes).
In this manner, mathematical operations can be performed on date and time values. Note that when using date maths, it is best to use the YYYY-MM-DD date format. Dates presented in other formats will be interpreted subject to the regional settings of the PC or Pocket PC.
DateTime Custom Points are not available in the Lite Edition.
