Follow-up Comment #1, sr#110989 (group autoconf):
Zack, isn't that essentially the code you wrote for
_AM_FILESYSTEM_TIMESTAMP_RESOLUTION in Automake (sanity.m4)?
for am_try_res in $am_try_resolutions; do
# Any one fine-grained sleep might happen to cross the boundary
# between two values of a coarser actual resolution, but if we do
# two fine-grained sleeps in a row, at least one of them will fall
# entirely within a coarse interval.
echo alpha > conftest.ts1
sleep $am_try_res
echo beta > conftest.ts2
sleep $am_try_res
echo gamma > conftest.ts3
# We assume that 'ls -t' will make use of high-resolution
# timestamps if the operating system supports them at all.
if (set X `ls -t conftest.ts?` &&
test "$[]2" = conftest.ts3 &&
test "$[]3" = conftest.ts2 &&
test "$[]4" = conftest.ts1); then
am_cv_filesystem_timestamp_resolution=$am_try_res
break
fi
done
