Constructors

SystemTime

Fields

systemTimeCurrent ∷ m RelativeTime
Get current time (as a RelativeTime)
For real deployment, this will take the current UTCTime and then subtract the SystemStart (see defaultSystemTime). Tests don't bother with a UTCTime and just work entirely in RelativeTime.
systemTimeWait ∷ m ()
Wait for SystemStart
For the real deployment, this waits for the current UTCTime to reach SystemStart. In tests this does nothing.
