Fixed version of qtime.c

[Ade Lovett]

After all those problems with NULL != "" in qtime, there does in fact appear
to be a *real* bug in qtime.

As Rchard Wexelblat <rwex at org.ida.cs> pointed out (thank you :-), any time
where the minutes are greater than 30 causes the wrong hour to be printed out.
E.g.
	7:35 will give 25 minutes to seven

Oops. Here is the amended qtime.c
