Documentation
Clock types. A clock may be system-wide (that is, visible to all processes)
or per-process (measuring time that is meaningful only within a process).
All implementations shall support
Realtime
.
Constructors
| Monotonic |
The identifier for the system-wide monotonic clock, which is defined as
a clock measuring real time, whose value cannot be set via

Instances
getTime :: Clock -> IO Seconds Source #
The
getTime
function shall return the current value for the
specified clock.
getRes :: Clock -> IO Seconds Source #
The
getRes
function shall return the resolution of any clock.
Clock resolutions are implementation-defined and cannot be set
by a process.
fromNanoSecs :: Integer -> Seconds Source #
Seconds from nano seconds.
toNanoSecs :: Seconds -> Integer Source #
Seconds to nano seconds.
