mrjedi,
Could you explain how to sync for 1 hour and 15 minutes, please. I have and S8500 with and S8300 LSP, both set to get time using NTP, but still get drift. This is a known issue with Avaya and is supposed to be corrected in software release 3.1.x, but am not ready to upgrade from 2.1 and want to get a more accurate time displayed.
