When does $ENGINE_UPTIME reach its limit?

About 596 hours until the max positive number is reached (0x7fffffff). However, it may continue on with 0x8000000 and continue to climb for another 596 hours until it reaches zero and then starts all over.
I've never actually run a test to see what it does at the 0x7fffffff point. The simplest thing would be to just continue through all the values with the sign bit on. So, if your usage algorithm simply computes differences between start and stop time, you should be able to use it for about 1193 hours before you will get a wrap-around issue. :lol:
Maybe someone has actually run the thing for 25 days or so and taken some data at the 0x7fffffff point? If so, perhaps they will share their findings with us :roll:
Rejoice,
Bob
