When running the following example $ /usr/bin/time /usr/bin/wc /etc/hosts The output is: 7 23 222 /etc/hosts 0.00user 0.00system 0:00.00elapsed 100%CPU (0avgtext+0avgdata 1844maxresident)k 0inputs+0outputs (0major+80minor)pagefaults 0swaps It should be more nicely formatted with linefeeds and tabs, something like (-f "%U\\tuser\n%S\\tsystem\\n%E\\telapses\\n%P\\tCPU\\n" "(%XK\tavgtext\\n %DK\\tavgdata\\n %MK\\tmaxresident)\\n%I\\tinputs\\n" "%O\\toutputs\\n(%F\\tmajor pagefaults\\n %R\\tminor pagefaults)\\n" "%W\\tswaps\\n"): 0.00 user 0.00 system 0:00.00 elapsed 100% CPU (0K avgtext 0K avgdata 1844K maxresident) 0 inputs 0 outputs (0 major pagefaults 80 minor pagefaults) 0 swaps (For this example, I illustrated one tab between value and description, moved the common units inside paranthesis, changed from lower case k to uppercase K to signify binary KibiBytes) I have been unable to check if this was changed in version 1.9, but the same bad default is shown on https://www.gnu.org/software/time/
