Hey tonyc. Thanks, you taught me something. I ran ./perl harness -v ../dist/Time-HiRes/t/utime.t and the output (trimmed out a little bit of non-relevant stuff for readability):

../dist/Time-HiRes/t/utime.t ..

It seems that the test code expected floats but got integers.

WRT the version of Debian I am running, I derived the version I reported in my post from the output of cat /proc/version, but the /etc/debian_version file contains 12.1. Hope that clarifies things.

Thanks again.
