Before this change backend types were printing incorrectly as the name
of the type, not what was defined by the Type() method.
This was not working due to not calling the Type() method. However
this needed to be defined on a non-pointer type due to the way the
options are handled.
Before this fix, the parsing code gave an error like this
parsing "2022-08-02 07:00:00" as fs.Time failed: expected newline
This was due to the Scan call failing to read all the data.
This patch fixes that, and redoes the tests
Similar to fs.Duration but parses into a timestamp instead
Supports parsing from:
* Any of the date formats in parseTimeDates
* A time.Duration offset from now
* parseDurationSuffixes offset from now
