[Coco] How to get time in DW4

[Bill Pierce]

Aaron, I've noticed the same time problem as Bob. If you wait just a minute or so, it gets corrected. It seems the time isn't being set at boot but is being set on the 60 sec interval. A lot of times, I'm rebooting from a crash while testing a new "C" compile and do a "make" right after I boot before the time gets reset and I get all kinds of weird times after "touch" sees a date much older than the last compile. I usually have to wait about a min, then everything is fine.

I think part of the problem is having the "date" command in the "startup" file. I think it's reading the time before OS9 has a chance to to reset it from the DW time signal. I was "sortta" investigating into this at one time due to OS9's clock loosing time on disk access untill DW's 60 sec interval resets it.

 The reason I was looking into it was that I was thinking of using the DW clock signal as a Midi timer (when DW is present) and it would give Midi a much more accurate clock. Of course any program using this would have to make a DW check and revert back to the old clock if there is no DW.

I found the clock request info in theDW spec. It seem $23 is the request code.

Can this be sent "raw" through "/N" ?  I know there would have to be code to interpret the return values which should be:

Byte 1: Current year minus 1900
Byte 2: Month
Byte 3: Day
Byte 4: Hour
Byte 5: Minute
Byte 6: Second.

With this, info, a "Time" request command could be written as I didn't see any such command in the "DW" or "UI" command lists.

Sounds like maybe another problem with nightly disks?  It should be
automatic, the dw3 clock module sets the clock to the current server
time every 60 seconds (when it works / gets loaded / ?)
