Conversion to and from text
utcTimeToText :: TimeFormat -> UTCTime -> Text Source #
Convert the specified time value to text, using the specified time format.
utcTimeFromText :: [ TimeFormat ] -> Text -> Maybe UTCTime Source #
Attempt to use each of the specified time formats to parse the given text.
Returns a time value that corresponds to the first matching format, or
Nothing
if none of the formats matched.
Time format specification
data TimeFormat Source #
Represents a particular way of representing a moment in time in text.
