 Each of these tickets is dealing with the same issue, which I summarized
 in [57035#comment:39]:

 >I'm thinking this area needs a deeper contextual dive as well as
 consideration and testing to raise confidence of no side effects or
 regressions being introduced. It'll also need more test coverage (happy
 and unhappy paths).
 >
 >The challenges:
 >* robust solution to handle all timezones include partial hour timezones.
 >>The `gmt_offset` can be a float/double for partial-hour timezones such
 as +5:30 UTC for India and Sri Lanka.
 >* review of what values `gmt_offset` should and could have.
 >* and cross-version compatibility for the PHP versions WP supports.
 >
 >I'm also curious of how this is solved in other projects.
 >
 Pulling it into 6.7 and self-assigning with intent to help shepherd the
 effort for these tickets.
