Defining timestamp fieldsA timestamp field can store date values from January 1, 0001 to December 31, 4000. Timestamps are measured in seconds.Important To avoid confusion when using dates in FileMaker Pro, always use four-digit years. For more information, see Conversion of dates with two-digit years.

• A timestamp field always includes a date and a time of day. You must specify formats for both date and time components to change the format of a timestamp. For more information, See Specifying formats for timestamp fields.
• Mathematical operations performed on timestamps are similar to those performed on time fields, and have a resolution of seconds (date fields have a resolution of days). Because one unit of timestamp is one second, to add one day's worth of time to a timestamp you would add 86400 (60 seconds to a minute * 60 minutes to a hour * 24 hours to a day) to the value in the field.
•
• The separators in time fields and the order in which the time parts appear depend on the system formats set for the file and the display format for the field. To change the display format for a field (for example, 11:09 PM or 23:09), set options in the Inspector in Layout mode. See Specifying formats for timestamp fields.
• When you select Insert menu > Current Time in an active timestamp field, FileMaker Pro inserts the full current date and time.
• When you select Insert menu > Current Date in an active timestamp field, FileMaker Pro inserts the current date only.
• To specify how data in a timestamp field displays (for example, to specify whether the value shows the day of the week or “AM” and “PM”), see Formatting and setting up field objects in Layout mode.
• If you are using FileMaker Pro Advanced, you can copy field schemas from one file and paste them into the same file or some other file. For more information, see Copying and pasting field schemas (FileMaker Pro Advanced).
