The time of cvs extraction is not what matters at all. Right, but the state of the CVS tree at the time of extraction does matter. So, if CVS generates the information based on the source information and not the time of day we have a solution.

Except in the case of CVSup, which wouldn't (shouldn't) know how to generate this RCS/CVS macro to modify files and essentially 're-create' the same information that CVS does. :( > However, this ignores the real problem which is that you don't care when the > stuff is EXTRACTED.

Aka, could it have something to do with the contents of the bottle, not when you opened it up? Just because you left it out overnight doesn't mean it's fresh. :) Nate
