mptsFromPosixSeconds :: Int64 -> PSTimestamp Source #

Construct PSTimestamp from amount of integral seconds since Unix epoch

mptsFromPosixSeconds2 :: Int64 -> Word32 -> Maybe PSTimestamp Source #

Construct PSTimestamp from amount of seconds and nanoseconds (must be \( \leq 10^9 \) ) passed since Unix epoch

mptsToPosixSeconds2 :: PSTimestamp -> (Int64, Word32) Source #

Deconstruct PSTimestamp into amount of seconds and nanoseconds passed since Unix epoch

mptsFromPosixNanoseconds :: Integer -> Maybe PSTimestamp Source #

Construct PSTimestamp from total amount of nanoseconds passed since Unix epoch

mptsToPosixNanoseconds :: PSTimestamp -> Integer Source #

Deconstruct PSTimestamp into total amount of nanoseconds passed since Unix epoch

mptsToUTCTime :: PSTimestamp -> UTCTime Source #

Convert PSTimestamp into UTCTime

mptsFromUTCTime :: UTCTime -> Maybe PSTimestamp Source #

Convert UTCTime into PSTimestamp

This conversion can fail (i.e. result in Nothing) if either the conversion cannot be performed lossless, either because the range of PSTimestamp was exceeded or because of sub-nanosecond fractions.
