Wireshark doesn't show the pcap header on packets, only the data, so it wouldn't show the bytes, correct. Doesn't mean they aren't there.

Looking at pcap.h shows pcap_file_header contains 'thiszone' which shows the offset from GMT to this time zone, and that pcap_pkthdr contains a struct timeval ts in addition to the caplen and len fields.
