How can I convince tcpdump to use UTC time instead of System Time in filenames?

In tcpdump you can specify a filename for log rotation using strftime syntax, for example, tcpdump -i en0 -w capture.%Y%m%d.%H%M%S.pcap. This will add the day/month/year/time to the filename when rotating files, based on the system time.

Is there any way to use UTC time instead?
