(the proper implementation of a monotonic clock), and
CLOCK_TAI does not work.
+RATIONALE
+ Previously, the best wait to sleep until a specific time
+ was to use date, sleep, and arithmetics in Bash. This is
+ very inconvenient, and only allows sleep over a monotonic
+ clock.
+
+ This progam was written so that the author could combine
+ it with mplayer to construct a custom alarm clock.
