[time-nuts] HP Z3801 Life time

[Rex]

I never saw the original message because, apparently, it was off-topic 
posted in one of the noisy threads I was deleting. But anyway...

 From the similar GPS 58503B manual:

:DIAGnostic:LIFetime:COUNt? RESPONSE
Returns the lifetime count, indicating the total powered-on time.
Range of the integer is 0 to 4,294,967,296 with a resolution of 1. Each 
count
represents three hours of operation.

If I did the math right, that allows for about 490,000 years. Probably a 
bit more than necessary.

The OP said,
"started at life time 13917 and after 145Hrs it shows 13965"
So that would be 13965 - 13917 = 48   x3 = 144 hrs

13965 x 3 = 41860 or about 4 3/4 years of on time.
