in thread Time::HiRes not that high on windows

Hi all

while reading this, I tested it on my XP (ActivePerl 5.8) and got this :

1130370142.0764
1130370142.07657
1130370142.07669
1130370142.07679
1130370142.07691
1130370142.07701
1130370142.07712
1130370142.07723
1130370142.07734
1130370142.07745

Has it maybe something to do with cygwin or have I missed something

Have a nice day

    Wow! A rave from the grave :)

    This thread relates to an very old version of Time::HiRes. Later versions use a different system API to allow much higher resolution. For further reading see thread at Perl -de1 weirdness. and particularly Re^4: Perl -de1 weirdness..

    The resolution under windows is now comparable at around the 7 microsecond mark (on my machine. It will vary somewhat with the speed of your cpu). Certainly faster than a Perl script can report it.

    Though the weirdness with Time::HiRes when running under the debugger persists into 5.8.6:

    C:\perl5.8.6\bin>.\perl -MTime::HiRes=time -le"print time() for 1 .. 1 +0;" 1130373293.29716 1130373293.29732 1130373293.29739 1130373293.2976 1130373293.29766 1130373293.29784 1130373293.2979 1130373293.29807 1130373293.29814 1130373293.29831 C:\perl5.8.6\bin>.\perl -de1 Loading DB routines from perl5db.pl version 1.25 Editor support available.
