– macOS limits (using filesystem HFS+): on macOS the minimum representable date is January 1st, 1904 GMT. The maximum representable date is February 6, 2040 at 06:28:15 GMT.
– Windows limits: the minimum representable date is January 1st, 1980. The maximum date is December 31, 2107.
– The timestamps are in local time.
– On macOS it may take some time (about 5 secs) before the change is visible in the Finder. On Windows you need to refresh a Window before you see the change.


Set Timestamp Modified [ Select ; $ErrorCode ;  "Mac HD:data:test.txt" ; 
			Timestamp ( Date ( 5 ; 09 ; 2017 ) ; Time ( 08 ; 59 ; 59 ) ) ]

This will set the modification date/time to May 9, 2017 at 08:59:59.

Example 2

We assume that in your FileMaker file the following fields are defined:

    gTheFile			Global, text
    gTimestampModified		Global, timestamp
    gErrorCode			Global, text

gFileSpec should contain the path to an existing file, for example “D:\Out.txt” (Windows) or “Mac HD:Out.txt” (Mac). gTimestampModified should contain a valid date/time. In a script add the following script step:

Set Timestamp Modified [ Select ; gErrorCode ; gTheFile ; gTimestampModified ]

This will set the file’s modification date/time to the value in the timestamp field.
