   typo, nanoseconds.

Thanks.  There is currently support in MIT Scheme for nanosecond-
resolution clocks; the best you get is microsecond resolution from
gettimeofday(2) with the nullary REAL-TIME-CLOCK procedure, although
it yields a number relative to the start of the process.  Adjusting
this to get a number of microseconds relative to some epoch is a
simple matter of programming, but since you wanted to combine it with
the number of seconds since the epoch anyway, this doesn't matter
