This code was presuming undue familiarity with the contents of the instr_time struct. That was already broken on Windows, and it's about to get broken on most other platforms as well. The simplest solution that preserves the current output definition is to just do our own gettimeofday() call here. Realistically, the extra cost is probably negligible in comparison to everything else that's going on in a pgbench transaction, so it's not worth sweating over. On Windows, the precision delivered by gettimeofday() is lower than one could wish, but this is still a big improvement over printing zeroes, as the code did before.
