valueparseIso8601 :: MonadFail m => String -> m UTCTime

Source#

Parse an UTC timestamp in extended ISO8601 format a standard UTCTime type. This function is useful to parse the "snapshot" identifier printed by cabal-install after a database update into a useable type. Combine with toEpochTime to obtain an EpochTime that can be passed to the Hackage DB reading code from this library.
