-/// "2019-05-15T14:30:00Z US/Central". The to_string method, and serde serialization will

+/// This is a wrapper around date time objects, using timezones from the chroon-tz database and
+/// providing string representation and parsing of the form "<RFC3339> <Timezone Name>", i.e.,
+/// "2019-05-15T14:30:00Z US/Central". The to_string method, and serde serialization will
+/// produce a string of this format. The parser will accept an RFC3339-only string of the forms
+/// "2019-05-15T14:30:00Z", "2019-05-15T14:30:00+00:00", and also an "RFC3339 Timezone Name"
