Does anyone know how the Amiga clock keeps track of time? I had a
strange situation which could either mean the Amiga is broken, or not
depending on how the Amiga keeps time. Seems that I noticed time on the
Amiga was going along at twice the normal rate. Watching the clock
program, or polling the system for the time all showed each second on
the system clock taking 1/2 a real second. Now, switching to another
power outlet in another room solved the problem, but I have never been
able to duplicate it again on the original outlet. If the Amiga keeps
track of time via the AC frequency, then it is possible (I think) that
inadequate grounding could explain this phenomena (My three prong
converters are not really connected to a ground yet). If, however, the AC
is converted to DC immediately on entrance and the AC frequency is not
used, then I may have an Amiga problem. Any comments would be
appreciated.

Ata The amiga keeps track of time based by counting AC transitions from the power supply (and therefore from the power lines). I bet that you have a defective socket or a really noisy line on that outlet. Neil Katin pyramid!amiga!neil
