Cisco Bug: CSCtd32009 - Time Master issues causing Drift/Jumps in times used by various SM syste
Jan 04, 2017
Known Affected Releases
Symptom: Due to a bogus time distrubuted via time master, unintended grooming can occur causing user video to be deleted before its expiration even though there is available storage space to retain it. Conditions: When configured for custom time, recieved from an AMS, TimeMaster can inadvertingly distribute a bogus time as received from the AMS. Analog Matrix Servers distribute time as an ascii string over a console port, which is recieved by the TimeMaster XVCR and then distributed to all other stream manager devices on the network. Prior to 5.3.11 there is no protection or sanity check against random bit errors in the ascii timestamp, which can cause the time to jump by weeks, months or years. If the groomer on an XVCR kicks off before the time is corrected (presumably by the next TimeMaster message) undesired grooming may result.
