Retrieving a Version by Date and Time: sccs get -c

In some cases, you do not know the SID of the delta you want, but you do know the date on (or before) it was checked in. You can retrieve the latest version checked in before a given date and time using the -c option and a date-time argument of the form:

-cyy [mm [dd [hh [mm [ss ]]]]]

For example:

$ sccs get -c880722120000 program.c
1.2
86

retrieves whatever version was current as of July 22, 1988 at 12:00 noon. Trailing fields can be omitted (defaulting to their highest legal value), and punctuation can be inserted in the obvious places; for example, the above line could be written as:

sccs get -c"88/07/22 12:00:00" program.c

Year 2000 issue. SCCS continues to use a two-digit year representation in the date format. Sun has adopted the proposed specification (XCU5) from the X/Open group that states that values of "yy" from 69 through 99 are to be interpreted as 1969 through 1999 respectively, and values of "yy" from 00 through 68 are to be interpreted as 2000 through 2068 respectively.
