[plt-scheme] gmt?

Is there any way to get gm time from plt?  Any equiv of cl
get-universal-time?  The problem with

(seconds->date (current-seconds))

is that it tells you the time in the time zone the computer
thinks it's in.  To get gmt from that you'd have to do ugly
date arithmetic.

Is there any way to get a time you could use to make timestamps
that you could exchange with another distant server?
