OK. Going back to Casper's problem, I remember from old posts that he
is using Void, Void packages a libskarnet built with
--enable-monotonic, and the man page says that CLOCK_MONOTONIC does
not count time that the system is suspended, so could that be the
reason of s6-log's incorrect timestamps after suspension or
hibernation?

On the other hand, as far as I can tell, GNU Coreutil's date(1) just
calls clock_gettime() with a CLOCK_REALTIME argument, so if that works
correctly after suspension or hibernation, in the absence of better
clock interfaces, maybe linking s6-log to a libskarnet build without
--enable-monotonic would work?
