Ben Schofield	e53aabd914	add datetime parser Add a relaxed datetime parser. This datetime parser functions by using `chrono`s own parsing utilities and a try/succeed approach to parsing. This implementation of the datetime parser has some drawbacks and some positives. On the positive side: - it was easy to implement - it is easy to add more datetime formats to In order to add additionally supported formats, a developer can add the required format string to the `format` mod in `parse_datetime.rs`, and then add it as a potential format to the relevant `fmts` vec. On the negative: - It is not easily customiseable beyond the supported `chrono` parsing formats. E.g., `chrono` does not currently support parsing offsets without trailing zeros. `from_str("UTC+1")` should return a valid response but `chrono` fails to parse this. - Because it is an attempt driven parser, it is likely not that performant. I have not done any performance testing as part of this change, but I would expect a custom parser to perform much better.	2023-06-03 09:58:36 -07:00
