getPOSIXTime -package:rebase

getPOSIXTime :: IO POSIXTime
time Data.Time.Clock.POSIX, time-compat Data.Time.Clock.POSIX.Compat, aws-cloudfront-signed-cookies Network.AWS.CloudFront.SignedCookies
Get the current POSIX time from the system clock.
getPOSIXTime :: PandocMonad m => m POSIXTime
pandoc Text.Pandoc.Class
Get the POSIX time. If SOURCE_DATE_EPOCH is set to a unix time, it is used instead of the current time.
getPOSIXTime :: IO POSIXTime
thyme Data.Thyme.Clock.POSIX
Return the current system POSIX time via gettimeofday, or getSystemTimeAsFileTime on Windows. See also getCurrentTime, getZonedTime.
getPosixTimeAsPosix :: IO PosixReal
hosc Sound.Osc Sound.Osc.Time
realToFrac of Clock.Posix.getPOSIXTime 
get_ct = getCurrentTimeAsPosix
get_pt = getPosixTimeAsPosix
(ct,pt) <- get_ct >>= \t0 -> get_pt >>= \t1 -> return (t0,t1)
print (pt - ct,pt - ct < 1e-5)
