data UTCTime :: *

This is the simplest representation of UTC. It consists of the day number, and a time offset from midnight. Note that if a day has a leap second added to it, it will have 86401 seconds.

Instances

Eq UTCTime
Data UTCTime
Ord UTCTime
NFData UTCTime
ToSQL UTCTime
FromSQL UTCTime	`FromSQL` instance for `ZonedTime` doesn't exist because PostgreSQL doesn't provide zone offset information when returning timestamps with time zone in a binary format.
PQFormat UTCTime
FormatTime UTCTime
ParseTime UTCTime
type PQDest UTCTime = PGtimestamp
type PQBase UTCTime = PGtimestamp

class Monad m => MonadTime m where
