I have no idea how to set back my sundial and my hourglass.
For the sundial you have to stand on the east side of the dial facing north, and then walk counterclockwise around it N times, where N equals your longitude W of Greenwich.
For the hourglass, well, duh – did you buy a Standard Time hourglass or a Daylight Saving Time hourglass? You can't
reset it, you just have to use the right one or you'll be an hour off. That's why they're sold in pairs, you know.
