krb5_timeofday, krb5_set_real_time, krb5_us_timeofday, krb5_format_time, krb5_string_to_deltat — Kerberos

krb5_set_real_time  sets  the  absolute  time  that the caller knows the KDC has.  With this the Kerberos
       library can calculate the relative difference between the KDC time and the local system time and store it
       in the context.  With this information the Kerberos library  can  adjust  all  time  stamps  in  Kerberos
       packages.

       krb5_timeofday()  returns  the current time, but adjusted with the time difference between the local host
       and the KDC.  krb5_us_timeofday() also returns microseconds.

       krb5_format_time formats the time t into the string s of length len.  If include_time is set, the time is
       set include_time.

       krb5_string_to_deltat parses delta time string into deltat.
