In CVS, all dates and times are processed by a version of the GNU
getdate function, which can
translate dates and times given in several different formats. Case is
always irrelevant when interpreting dates. Spaces are permitted in
date strings, but in the command-line client a string with spaces
should be surrounded by quotes. If a year is 0 to 99, it is considered
to be in the twentieth century.
If a time is not given, midnight at the start of the date is assumed. If a time zone is not specified, the date is interpreted as being in the client’s local time zone.
