I use code based on the Olson database to figure out concomitant civil times. I don't think Boost has a module that includes this full database (that is, knowledge of how the time is changed when the rule was different in different years).

My software records time events on the computer and it does it using whatever timezone and daylight saving time settings are on this computer. I realized too late that, while storing timestamps, I am not accounting for this daylight adjustment process. So, if hypothetically speaking, the daylight adjustment happens today at 9:00 am and I am writing my timestamps every second I will have something like that: … 8.58 8.59 9.00 10.01 (without timesaving should be 9.01) 10.02 (without timesaving should be 9.02) … When I am reading my timestamps back I am constructing timezone and using it for timestamps manipulation std::string gmt = (boost::format("TMZ%1% TMS1:00:00,M3.2.0/02:00:00,M11.1.0/02:00:00") % gmtoffset).str(); , but this one-hour gap persists, as I now think it should.
The question is: is it possible to do manipulation with datetime library to remove this gap without hard-coding one hour removal after specific date/time of daylight saving time?
