Hi Robert,
As you probably know the Clarion FORMAT command does not format times greater than 23:59.
In my own programs I've written a small procedure that formats the string for me, and then I just use a string format when displaying that on a window.
The @p or @k format should work (although I've not tested it, and there may be some issues) but I don't think they really help in this case. They don't convert the underlying number to "time". So, for example, if the time (long) value is 720001 (about 2am) and you format it with @K##:##K, you just get (at best) 72:00 which is useless.
That said, there's quite a lot of infrastructure around pictures already in nettalk, so I think overcoming the 23:59 limit would be do-able. I'll see what can be done.
cheers
Bruce
