using 183.38 ->H .8 x ->H.MS (via the Convert menu on the HP42S)

Legendary 67 and Free42 return 146:44:24, the same as Excel, while
HP-15C returns 146:54:56

I haven't had a chance to check on real hardware but was under the impression that all these emulators used real ROMs.

Will check on real hardware, but in the meantime, any ideas why the HP-15C might be different?

Whilst the actual answer is 146h 54m 24s

Did you make a typo for the 67 & Free42?
Free42 on my Android phone correctly returns 146.5424

Unfortunately I don't have a 15C (real or emulator) at hand to check at the moment.
