Well, the man page says:
If the format string does not contain enough conversion specifications to
completely specify the resulting struct tm, the unspecified members of
timeptr are left untouched. For example, if format is ``%H:%M:%S'', only
tm_hour, tm_sec and tm_min will be modified. If time relative to today
is desired, initialize the timeptr structure with today's date before
passing it to strptime().
This is a clear contradiction with the actual code since, if the %s or %Z
specifiers are used then GMT processing is assumed (unconditionaly for the first
and conditional upon a GMT string in the second case) and the rest of the fields
are filled in. This does not occur if a non-GMT time is used. This strikes me as
inconsistent. Either the rest of the fields should be unconditionaly filled in
or not. Your suggestion seems reasonable, but I don't know if there are any
Standards issues involved.
I'll supply a patch to freebsd-standards, and if no one objects, commit it.
Cheers
