Fix for Daylight Savings Time bug on Windows
Fix for Daylight Savings Time bug on Windows

The bug is caused by calling stat on a file which exists in a
different "DST state" from current time. To resolve the issue, the
syscalls test will use a time set to one hour in the future.

There should, twice a year, be a bot failure (Windows exclusive) for
a one hour period around the middle of the night, but this seems
like an acceptable flake.
