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

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 source file to the WHIP! data was last modified
GUID A globally unique identifier (GUID) represented
by an alpha-numeric description generated to capture the modification time
of the source file
Details
Some WHIP! data reading applications may need to "know" when the source file
that was used to generate the WHIP! data was last changed. The WHIP! data
generating application can satisfy this with the SourceModified opcode:
(Created 820497600 'January
1, 1996' C0176e42-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 source
modification time opcode, which by convention should be nested inside a
Define
Drawing Information Block opcode.
Default
By default no source drawing modification time
is defined, which is equivalent to
(SourceModified
0 unknown unknown)
