I now have an idea of what might be going on here: it looks like the usual binary roundoff problem.
This 15C simulator seems to use binary arithmetics as most computer hardware does. This means that 183,38 cannot be represented exactly as a binary value and its decimal equivalent may be 183,37999999999... While decomposing the input into hours, minutes and seconds this in turn is interpreted as 183 hours, 37 minutes and 99,99999... seconds. Et voilà: this indeed equals 183,6444444... hours.

Case closed ?-)

Yet Free42 binary (of which I must be the only user?) gets it right ;-)
