Synopsis

date time checkers

Right (Refined2 {r2In = 2018-09-14 02:57:04, r2Out = "2018-09-14 02:57:04"})
>>> prtEval2 @(Dtip LocalTime) @'True ol "2018-09-99 12:12:12"
Left Step 1. Initial Conversion(ip) Failed | ParseTimeP LocalTime (%F %T) failed to parse

time checkers

base n

type BaseN (n :: Nat) = BaseN' n True Source #
