Max Value for 32bit Timers

[prwatE120]

Are we agreed that the data in the 32bit Hours/Lamp/Lamp Strike counters is unsigned ? ie max value is 0xFFFFFFFF ?

As far as I can see we do not explicitly state this anywhere in the document - apologies if I have missed it.

Yes. I can't think of any situation where there would be negative lamp hours, and anything other than an unsigned integer would only lead to confusion.

Yes, everything should be unsigned values so that the max value should be 0xFFFFFFFF.

It would also be a good idea for these type fields to not roll over if they exceed the 0xFFFFFFFF value and instead just remain at that Max value.

Just a note that this was discussed at the Jan 19th 2007 Task group meeting in Dallas and that Scott's response reflected the consensus of the group at that time.
