Minimal complete definition
Methods
substituteTimeSpecifier :: Proxy t -> TimeLocale -> Char -> Maybe String Source #
Since: 1.9.1
parseTimeSpecifier :: Proxy t -> TimeLocale -> Maybe ParseNumericPadding -> Char -> ReadP String Source #
Get the string corresponding to the given format specifier.
Since: 1.9.1
Arguments
| :: TimeLocale | The time locale. |
| -> [(Char, String)] | Pairs of format characters and the corresponding part of the input. |
| -> Maybe t |
Builds a time value from a parsed input string.
If the input does not include all the information needed to
construct a complete value, any missing parts should be taken
from 1970-01-01 00:00:00 +0000 (which was a Thursday).
In the absence of %C or %Y, century is 1969 - 2068.
Since: 1.9.1
