DiffTime

data DiffTime Source #

This is a length of time, as measured by a clock. Conversion functions will treat it as seconds. It has a precision of 10^-12 s.

Compact timestamp

timestampMicrosecondsLow32Bits :: Time -> Word32 Source #

This is a slightly peculiar operation: it returns the number of microseconds since an arbitrary epoch, modulo 2^32. This number of microseconds wraps every ~35 minutes.

The purpose is to give a compact timestamp (compact to send over the wire) for measuring time differences on the order of seconds or less.
