Short of a full time and date library, a single procedure

(current-seconds)

returning the epoch time in seconds, possibly as a real number, would be useful and is sufficient to implement a full library (though access to the host system's timezone would be desirable in that case).

Note for systems with no clock or concept of time, this could be made optional. Alternately, it could simply be a counter, sufficient to show relative ordering of events but not exact durations.

WG1 voted to provide an optional current-seconds procedure.

Which epoch was left unspecified in the winning ticket, so should be unspecified in the standard.
