The problem that CAD time for the ESD alarms is not at the exact time there is shift in time around 8 minutes. For example the exact time of X alarm is 5:10 AM. In CAD, I found the time of the same alarm is 5:02 AM. Please help in this regards to fix the time stamp. *** Confidentiality Notice: This e-mail, including any associated or attached files, is intended solely for the individual or entity to which it is addressed.
