no microseconds timestamp from strace -t -u

[Ilya Basin]

Hi List. From Cygwin's `strace -h`: "-u, --usecs                  toggle printing of microseconds timestamp".

However, the output only has seconds precision:

    $ /usr/bin/strace.exe --version
    strace (cygwin) 3.6.4
    $ /usr/bin/strace.exe -t -u /bin/true.exe
    00:00:00 [main] true 6557 pinfo::exit: Calling ExitProcess n 0x0, exitcode 0x0

Is it a stub feature?
