editpcap - Add option to interpret -A and -B options as UTC Time
Description
editpcap use local time to read -A and -B options. This makes scripts Timezone dependant and also generates other sideeffects, such as when the "TZ" environment variable is set on windows.
I suggest to:
- add an option to indicate that the times -A and -B should be read as UTC time.
- enable providing a numeric timestamp (if that is not already possible). The simpliest implementation would be to use EPOCH (POSIX wise).
