Actually, the man page does not say anything about the behavior across
suspends, and ...
CLOCK_REALTIME
System-wide realtime clock. Setting this clock requires appro-
priate privileges.
CLOCK_MONOTONIC
Clock that cannot be set and represents monotonic time since
some unspecified starting point.
I'd understand both those wordings the same way! Well, I suppose
"cannot be set" means that at least humans can't willingly interfere with
it, but maybe something else can.

"Monotonic" means "always goes in the same direction", not "never
skips".
