Documentation

class Show a => MyShow a where

Methods show_ :: a -> String Instances MyShow String Show a => MyShow a

print_ :: (MonadIO m, MyShow a) => a -> m ()

Like print, except that Strings are not escaped or quoted.

mkUTCTime :: (Integral a, Real b) => a -> a -> a -> a -> a -> b -> UTCTime

Convenience for making UTCTimes. Assumes the time given is already UTC time i.e. there's no timezone adjustment.

mkCalTime :: Integral a => a -> a -> a -> a -> a -> a -> CalendarTime

int64ToDateParts :: Int64 -> (Int64, Int64, Int64, Int64, Int64, Int64)

datePartsToInt64 :: (Integral a1, Integral a2, Integral a3, Integral a4, Integral a5, Integral a6) => (a1, a2, a3, a4, a5, a6) -> Int64

calTimeToInt64 :: CalendarTime -> Int64

int64ToCalTime :: Int64 -> CalendarTime

int64ToUTCTime :: Int64 -> UTCTime

wordsBy :: (Char -> Bool) -> String -> [String]

skipNonMatch :: (Char -> Bool) -> String -> [String]

positions :: Eq a => [a] -> [a] -> [Int]

pgDatetimetoUTCTime :: String -> UTCTime

pgDatetimetoCalTime :: String -> CalendarTime

pgDatetimeToParts :: String -> (Int, Int, Int, Int, Int, Double, Int)

utcTimeToIsoString :: (Integral a, Integral b) => UTCTime -> String -> (a -> a) -> (b -> String) -> String

utcTimeToPGDatetime :: UTCTime -> String

utcTimeToIsoDatetime :: UTCTime -> String

utcTimeToOdbcDatetime :: UTCTime -> String

calTimeToPGDatetime :: CalendarTime -> String

Assumes CalendarTime is also UTC i.e. ignores ctTZ component.
