- RosGetTimeFormat(): replace "if (!cchTime) ; else ..." by "if (cchTime)" and adjust comment

Browse source 
- Kohn Emil Dan <emild@cs.technion.ac.il>:

1) RosGetTimeFormat() has a small bug. The last statement should be
return nPos;
and not
return cchTime;

2) GetTimeFormatA() is not implemented. I have written an implementation
for it, which calls GetTimeFormatW(), and converts the string parameters
back and forth.

(committed with adjustments for correct error handling)
