For aggregated logging, pg_bench supposed that printing the integer part of INSTR_TIME_GET_DOUBLE() would produce a Unix timestamp. That was already broken on Windows, and it's about to get broken on most other platforms as well. As in commit 74baa1e3b, we can remove the entanglement at the price of one extra syscall per transaction; though here it seems more convenient to use time(NULL) instead of gettimeofday(), since we only need integral-second precision. I took the time to do some wordsmithing on the documentation about pgbench's logging features, too. Discussion: https://postgr.es/m/8837.1483216839@sss.pgh.pa.us
