"TIME" as an integer..

If you telnet into the master and do a ‘msg on’ each message is time stamped with the number of milliseconds since the program has been running but that number has nothing to do with the time of day.

I don’t know of any variable we can get at with Netlinx to obtain the time of day with the precision you’re looking for. Maybe Duet has something?

Rod,
A need for something similar came up recently and the code below is as close as I could get - but it isn't 100%. To create the millisecond field, I essentially created a repeating timeline that would occur more than once a second. Your testing will show the sweetspot of the timeline results in 60 passes and is repeatable. At its smallest time interval, the master (under no other load) can do this more than 1500 times per second, but that number goes down as load on the processor increases to do the rest of your system program. I was never able to achieve 100 steps (a true millisecond) reliably. There are too many unknown variables affecting the results - but 60 is achievable.

If you need UNIX timestamps, I wrote an include that is a part of the NetLinx Common Library to handle conversion to/from AMX time and to format time strings using UNIX timestamps. Not sure if you may need that in addition to sub-tenth-second timing.
