Clarification!! .. The old ATT PC6300 clock problem revisited

[Graham Brand]

Thanks for the responses received so far. However, I should have been a 
bit more specific. The clock on my PC6300 **does** work properly! The 
problem is that this program (DacEasy) does not obtain the same value
for the time as I do when I type "time". One respondent suggested that
programs calling the bios directly may obtain different results due to
differences in the bios implementation. Can anyone out there elaborate?
Are these differences documented somewhere and, more importantly, is 
there a "fix"?
