Fix git commit date string formatting

[fearnoeval]

I noticed that the Git dates are formatted with two timezones due to the way time.Time.String() is implemented. This change outputs the date in a similar, almost-RFC3339 format, but with the timezone only appearing once.

The way that Go's date formatting works makes me a bit uncomfortable, but it must work well enough given that all of the built-in date formats use it, so I followed the same pattern. The date used in the implementation is the one used by Go's time.RFC3339 since the string being output is similar.

Example

// Before
2023-03-08 15:55:42 -0500 -0500

// After
2023-03-08 15:55:42 -0500

Thanks for the contribution, this looks good to me and would close #1047

Could you also update ScanStaged with the same logic?

My mistake; the change is made in ScanStaged now as well.
