John Rogers (JohnRo) 25-Mar-1991
|
||
|
|
|
||
|
|
Environment:
|
||
|
|
|
||
|
|
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
|
||
|
|
Requires ANSI C extensions: slash-slash comments, long external names.
|
||
|
|
|
||
|
|
This code assumes that time_t is expressed in seconds since 1970 (GMT).
|
||
|
|
ANSI C does not require this, although POSIX (IEEE 1003.1) does.

Created as part of RpcXlate TOD (time of day) tests.
|
||
|
|
26-Feb-1992 JohnRo

||
|
|
Extracted this routine for general use.
|
||
|
|

|
RAID 2920: Support UTC timezone in net code.
|
||
|
|

|
||
|
|
RAID 3556: Avoid failure if ctime() returns NULL.
|
||
|
|
04-Mar-1993 JohnRo
|
||
|
|
RAID 12237: replicator tree depth exceeded (add display of FILETIME
|
||
|
|
and LARGE_INTEGER time).
|
||
|
|
16-Apr-1993 JohnRo
|
||
