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().
