UTC DateTime Conversion in Table Chart

Hello All,

I have a use case where i am trying to convert Two UTC DateTime columns into EPOCH Time get the difference between both and then Convert EPOCH time to EST Time.

However, at the time of sending field of UTC time from Google Cloud Monitoring to Grafana it changes the format and displays less information as it’s shown in the screenshot below, would appreciate if there’s any suggestion on how this can be fixed and this use case can be achieved?
