Define Drawing Modification Time - DEPRECATED
Purpose
The Define Drawing Modification Time function provides information
to WHIP! data reading applications about when the WHIP! data was last modified.

Defines
when file was last changed |
Time The number of seconds elapsed since midnight
(00:00:00), January 1, 1970, coordinated universal time (GMT)
Desc Any humanly readable description of the time
when the file was last modified
GUID A globally unique identifier (GUID) represented
by an alpha-numeric description generated to capture the modification time
of the WHIP! data. When WHIP! data is initially created, the
creation and modification GUIDs match.
Details
Some WHIP! data reading applications may need to "know" when the
WHIP! data was last changed. The WHIP! data generating application can indicate
this with the Modified opcode:
(Created 820497600 'January
1, 1996' C0176e40-dc10-11d0-bb09)
Notes
WHIP! data reading applications should not expect to be able to parse the
Desc
argument, though it could be shown to a user.
WHIP! data should contain at most one occurrence of the modification
time opcode, which by convention should be nested inside a Define
Drawing Information Block opcode.
Default
By default no drawing modification time is defined, which is equivalent
to
(Modified 0 unknown unknown)
