Comment 83 for bug 365065

My inclination would have been to use GLib's GDate, and then worry about moving away from GLib as a separate step. I don't think dates are rocket science; I could probably implement a reasonable API for the Gregorian calendar in plain C fairly quickly. I'm not sure if anything is needed besides string-to-date, date-to-string, increment/decrement date by n days/weeks/months/years. Leap years need to be implemented correctly but that is probably the only complication. But the point is that once the code uses GDate, it would be relatively easy to find-and-replace that by some other appropriate implementation. But the initial conversion to GDate (or equivalent) is harder.
