* print_timespec.c (print_timespec_t_utime): Use sprinttime_nsec to format a string representation of time, use tprints_comment to print it as a comment. * print_timeval.c (print_timeval_t_utime): New function. (print_timeval_utimes): Use it instead of print_timeval_t. [ALPHA] (print_timeval32_t_utime): New function. [ALPHA] (print_timeval32_utimes): Use it instead of print_timeval32_t. * tests/futimesat.c (print_tv): Update expected output. * tests/utimensat.c (print_ts): Likewise. * tests/xutimes.c (print_tv): Likewise.
