Summary: QDateTime::fromMSecSinceEpoch uses Qt::LocalTime by default. This involves an expensive localtime conversion. So instead force things to use UTC, as there is no need for timezone information when tracking durations. This is especially noticeable on Bedrock Linux, which uses a Fuse mounted /etc, which is slower than a plain /etc and causes quite some slowdown there. See https://github.com/bedrocklinux/bedrocklinux-userland/issues/140 for details. Test Plan: The screenedge unit test still passes.
