Package contents

datetime accepts a strptime-style format string, and creates a regular expression to match it. You can choose the locale for matching (month names differ between locales), and whether the regex is used for input or output (input needs to be less strict).

iso_date, iso_time and iso_datetime provide regexes to match ISO 8601 standard dates and times.

Constants are available for date components. For example, SECOND matches seconds, TIMEZONE matches timezones, etc.
