Changelog

1.0.0

Change parse_datetime to no longer assume time. Previously, it would assume 00:00:00 if it could not be parsed. This is replaced with an opt-in option assume_time. See next point. If you relied on this, to upgrade add the option; eg: DateTimeParser.parse_datetime(string, assume_time: true)
Change parse_datetime to no longer convert DateTime to UTC timezone. If you relied on this, to upgrade add the option; eg: DateTimeParser.parse_datetime(string, to_utc: true)
Change parse_date to no longer assume a date. Previously, it would assume the current date, and replace the found information from the string. This is replaced with an opt-in option of assume_date. If you relied on this, to upgrade add the option; eg: DateTimeParser.parse_date(string, assume_date: true)

Fix a UTC conversion bug between Daylight/Standard time (#20). If you're using an earlier version and converting to UTC, please upgrade to >= 1.0.0-rc2 immediately.
Fix an epoch subsecond parsing bug (#16) (thanks @tmr08c)
Updated for compatibility with Elixir 1.10.0

Add parse/2 that will respond with the best match. This function accepts all options introduced below.
Change parse_datetime/1 to parse_datetime/2 to accept options:
- assume_time: true | %Time{} | false with the default of false.
Change parse_date/1 to parse_date/2 to accept options:
- assume_date: true | %Date{} | false with the default of false.
Add support for parsing negative epoch times. (#24) (thanks @tmr08c)
Add bang variants, parse!/2, parse_datetime!/2, parse_time!/2, and parse_date!/2
Added parsers: [] option to add or disable parsers. This is helpful if you are don't want to consider Serial or Epoch timestamps.

Validate days of month. Previously it would allow invalid days such as Feb 30. Now it will check if the year is a leap year and allow up to 29, and otherwise 28 for Feb. It will also reject day 31 on months without 31 days.

Fix PM 12-hr conversion. The bug would convert 12:34PM to 24:34 which is not valid
