Comment 7 for bug 600803

So, Inno also create another problem for us by rounding the timestamp to the nearest even second, in the name of FAT compat:

Disabling that as well should finally fix this bug... for everyone except those still on FAT filesystems. To cover them as well, we'd have to round the timestamps of all plugin py files prior to bytecode compilation.
