How do you make Alarm Value Time Stamp Work?

I can not get the system to pull the alart time from the value. I had it working once, but its not working now that I tried to move the tag definition to the live system.

I am pulling in a LONG value that represetnst the time in microseconds that the alarm tripped. I have another tag that looks at the same value as a Date datatype and it shows the Date from the PLC value (set to 2 hours earlier to help in trouble shooting). But I can not get the Date typed tage to have an alarm that work. The long tag trips the alarm, but only shows the system date for the alart time. What should I look at to fix this?
