First, think hard about whether you really need that. The gnc_localtime function will fill in the struct tm correctly for the local timezone with the correct DST. That's what the date display functions in gnc-date.h use and you should probably be using them. If you're sure that you really need the offset, the best you can do in C is to call gnc_localtime and gnc_gmtime with the same time64 and get the difference between the two returned structs tm. It will be corrected for the In C++ you can include gnc-datetime.hpp and construct a GncDateTime from your time64 and call its offset() member function. In both cases the result will be correct for the DST at the time.
