That's a neat approach, however, it won't work for this one:
>  strptime("14h00", format="%Ih%M")
[1] NA

But this will:
>  strptime("14h00", format="%Hh%M")
[1] "2008-06-23 14:00:00"

However (again), *it* also won't work here:

>  strptime("23h", format="%Hh%M")
[1] NA

So it's back to the strsplit method for it unless you can get a zero
after the 'h', and the best way of doing that would depend on how your
real data is being entered.
