SUMMARY
=======

This article describes how to add or subtract time with a DateTime field. Time,
in seconds, can be added or subtracted with a DateTime data type field. Time
carries over from seconds to minutes to hours to days and to years. There are no
adjustments in this sample for a leap year. This is an example and you may want
to add additional functionality if time calculations are a large part of your
application.

MORE INFORMATION
================

When you add or subtract time with a DateTime field, the value(s) to add or
subtract will be calculated with seconds.

Example to add an hour:

     HourFromNow = Datetime() + 3600

-or-

Example to subtract a week:

     WeekAgo = Datetime() - (7*24*3600)
