glib/gio/tests/g-file-info.c
Ross Burton 289f8be1b3 gio/tests/g-file-info: don't assume million-in-one events don't happen 
The modification time test creates a file, gets the modification time in
seconds, then gets the modification time in microseconds and assumes
that the difference between the two has to be above 0.

As rare as this may be, it can happen:

$ stat g-file-info-test-50A450 -c %y
2021-07-06 18:24:56.000000767 +0100

Change the test to simply assert that the difference not negative to
handle this case.
