Hi Armin
This is the Time specified by CISCO Call Data, it is specified as UTC,
Maybe
your suggestion for conversion is correct.
"UTC" is simply a timezone offset (of 0). It's not a binary time format.
The value you have has a specific format, and until you know what that
format is, your question can't be answered. You've have to consult the
Cisco documentation for that.
Once you've figured out the format and determined a correct conversion
from the integer to an actual DateTime value, then Armin's suggestion for
specifying the storage for that value will apply.
