Re: [boost] [date_time] boost time is lacking a big bang

My generic library code has no problem with the 'value nature' of built in types. Because from the initial default constructed value

unsigned int x = int(); // x = 0 you can reach ++x // x = 1 ... ++x // x = 2^32

and thus all values of the types set of values.

This is not the case for boost::date_time objects like e.g. ptime

Nor is it the case for floating point numbers. Nor, technically, for signed numbers, where overflow is impl-defined (or worse, afaik).
