Subject: Update the "Error converting time" tests for packet times
X-Git-Url: https://git.tcpdump.org/tcpdump/commitdiff_plain/b84bd2b4b55067d1eea6181e1a09043ac093d48c

Update the "Error converting time" tests for packet times

Replace 0x80000000 mask test on tv_sec by a test on tv_sec
negative in ts_date_hmsfrac_print() and ts_unix_print().

Replace the error message by "[timestamp < 1970-01-01 00:00:00 UTC]"
