Subject: Add time offset field to the os_context structure.  This offset is
X-Git-Tag: krb5-1.0-beta6~1208
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=b9b39d222667df44c6311ae8c5857218338642ac;p=krb5.git

Add time offset field to the os_context structure.  This offset is
added to the system clock time to produce the "true" time.

Added prototypes for the functions which manipulate the time offset
structures: krb5_set_real_time(), krb5_set_debugging_time(),
krb5_use_natural_time(), krb5_get_time_offsets(), and
krb5_set_time_offsets().
