 This R package has three functions for dealing with dates.
 
--   `parse_iso_8601` recognizes and parses all valid ISO 8601 date and
-    time formats. It can also be used as an ISO 8601 validator.
--   `parse_date` can parse a date when you don’t know which format it is
-    in. First it tries all ISO 8601 formats. Then it tries git’s
-    versatile date parser. Lastly, it tries `as.POSIXct`.
--   `format_iso_8601` formats a date (and time) in specific ISO 8601
-    format.
