Converts a string to a Time.
The string is assumed to be an ISO-8601 time representation in extended format. For example, 05, 05:30, 05:30:00, or 05:30:00.123456789. The output of Time.toString can be safely parsed using this method.
05
05:30
05:30:00
05:30:00.123456789
Converts a string to a Time using a specific parser.
A set of predefined parsers can be found in DateTimeParsers.
