I'm not at home, don't have the Dev CD at hand and can't remember all units names but:
- VBlank
- MicroHz
- EClock
... ( I remember there are 5 units...)
...
Can someone tell me what hardware each unit actually uses ?

The other two units are WaitUntil and WaitEClock.

I think the timer.device uses a CIA timer on classic Amiga and uses the internal PowerPC timer on AOS 4. (Except for VBlank which obviously uses the graphics chip to indicate when the vertical blank has been triggered.

Yes, but I had the impression the EClock and MicroHz used diferent hardware. I remember they mention in the Devices Manual that the EClock was the most accurate one...

Both EClock and MicroHz use CIA.

You have to love the incorrectly used term "MicroHz". It implies a granularity of 1000 seconds! Very useful... :lol:
