strtotime() is highly unreliable in my experience, it just tries to make the
best of it.
A whopper of a regex and preg_replace could try to take care of it, but it
is a lot of work to catch all possible formats as described.
Personally, I wouldn't consider even writing this kind of code, unless
forced by an already existing badly configured database.

If I'd write the required script/application/whatever I'd make it impossible
to enter values like this. In a webpage I would create 2 simple select
lists: one with hours and one with minutes, takes care if the whole deal.
Controlling user-input is more reliable and a hell of a lot less work
compared to guessing what users are trying to do.
