Return value is hours * 3600 + minutes * 60 + seconds in UTC.

The underlying function in the XTRA is GetSystemTime:

|
|
|
|
Safecrackers only needs the number of seconds since the start of the game.
|
|
Since not all platforms that run ScummVM have a clock, it's implemented as
|
|
the number of seconds since the start of ScummVM.
