It's already 20 minutes off. I only use it for reference to itself.
Oh stuff I set it to -0.666 and now it's only 35 seconds off
It's off by only one second at -0.656
The change in offset should be -1 from what it was before. If you had it at 0, make it -1, or if at 1, set it to 0, et cetera.
Unless CDT is different in which case ehhhh.
