I'm attempting to use CreateTimeSpan() to hold information about how long my system will be down for maintenance given a starting date and time, and I've been running into a few interesting issues. I'd have thought that this would be a simple matter, as adding a timespan to an existing time stamp would be a useful mechanic, but it seems as though there are some hidden gotchas and, perhaps, some outright bugs.
