示例1: get_unix_time_from_time_string

"""Convert a datetime string into a unix timestamp.
The datetime_string must match DATE_TIME_FORMAT_EXTENDED above,
which is the extended ISO 8601 year-month-dayThour:minute:second format,
plus a valid ISO 8601 time zone. For example, 2016-09-07T11:21:00+01:00,
2016-12-25T06:00:00Z, or 2016-12-25T06:00:00+13.
isodatetime is not used to do the whole parsing, partly for performance,
but mostly because the calendar may be in non-Gregorian mode.
