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

(SourceCreated |

Defines when
the source file of the WHIP! data was generated |
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 of the WHIP! data file was generated
GUID A globally unique identifier (GUID) represented
by an alpha-numeric description generated to capture the creation time
of the source file
Details
Some WHIP! data reading applications may need to "know" when the source of
the WHIP! data was created. The WHIP! data generating application can indicate
this with the SourceCreated opcode:
(Created 820497600 'January
1, 1996' C0176e41-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
creation time opcode, which by convention should be nested inside a Define
Drawing Information Block opcode.
Default
By default no source drawing creation time is defined, which is equivalent
to
(SourceCreated 0 unknown unknown)
