Timestamp points allow the user to easily record the current time (and optionally date) by simply tapping a box.
On-screen, Timestamp points appear as a caption followed by a time box. Tapping the box will record the current time and/or date. To save space, the entry box can be configured inline, where it is displayed to the right of the point's caption.
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.
Timestamp points can also be configured to record the current time automatically as soon as they are first shown on-screen, and optionally prevent further modification of the value.
If a Timestamp 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 Timestamp 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, such as subtracting the difference between two Timestamp points to determine the number of minutes taken to complete part of a project.
Note that when using date maths, it is best to use the YYYY-MM-DD date format. Dates presented in other formats may not be interpreted correctly.
