It's just system time. $ date; KRB5_TRACE=/dev/stdout kvno user Fri Apr 3 10:58:03 EDT 2020 [...] [12194] 1585925883.499498: Retrieving u...@krbtest.com [...] [...] $ date -d '@1585925883' Fri Apr 3 10:58:03 EDT 2020 Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos

Whoops, I copied the wrong name; the public interface has docs at http://web.mit.edu/kerberos/krb5-1.18/doc/appdev/refs/api/krb5_us_timeofday.html and peeking at the source it's a gettimeofday()-like on unix-like systems. So the unix epocy conversion ought to be working, in my reading, yes. -Ben On Fri, Apr 03, 2020 at 08:21:39AM -0600, Todd Grayson wrote: > Ok but does that mean Unix Epoch time conversion should be working, or is > there some other form of secret decoder ring that is used to translate to > system time?

Re: What form is the timestamp in the KRB5_TRACE log (and why)
Ok but does that mean Unix Epoch time conversion should be working, or is there some other form of secret decoder ring that is used to translate to system time? In troubleshooting/debugging scenarios, being able to associate the timestamps from the KRB5_TRACE that has been running over an extended period with external services integrating with kerberos would be... handy? I can find no real references on krb5_crypto_us_timeofday() other than a select set of developer comments within the source code, and a whole bunch of spam advertising sites representing it and other source code segments?
