So I think your best bet might be to customize your boost install by changing the greg_year specification to allow dates prior to 1400. The 1400 is a sort of...

So I don't think the issue here is inexactness -- in fact it is exact. You'll note that in all test cases here the '.5' has been rounded up because...

The docs are ‘right’, but incomplete. If the fractional seconds are 0 then it is omitted - that’s probably the report your receiving. I have a version if the function...

I'm not sure what the confusion is. The function calls gmtime to assign the result pointer and then returns it? Also this is really an implementation detail of the library,...
