About timestamp fields
Use timestamp fields to store a date and time together to reference a fixed point in calendar time. Timestamps are measured in seconds.
Notes
•FileMaker Pro stores timestamps as the number of seconds since midnight on January 1, 0001. Therefore you can calculate timestamps before or after a given timestamp by subtracting or adding a number of seconds. For example, in a
calculation field whose result is a timestamp, the following formula calculates the timestamp one day (60 seconds to a minute * 60 minutes to a hour * 24 hours to a day = 86400 seconds) after the value in a timestamp field named TimestampStarted:
TimestampStarted + 86400
•The minimum and maximum values of a timestamp are 1/1/0001 12:00 AM and 12/31/4000 11:59:59.999999 PM.
