  class Foundation_API Timezone
  
This class provides information about the current timezone. { public: static int utcOffset(); Returns the offset of local time to UTC, in seconds. local time = UTC + utcOffset(). static int dst(); Returns the daylight saving time offset in seconds if daylight saving time is in use. local time = UTC + utcOffset() + dst(). static bool isDst(const Timestamp& timestamp); Returns true if daylight saving time is in effect for the given time. Depending on the operating system platform this might only work reliably for certain date ranges, as the C library's localtime() function is used. static int tzd(); Returns the time zone differential for the current timezone. The timezone differential is computed as utcOffset() + dst() and is expressed in seconds. static std::string name(); Returns the timezone name currently in effect. static std::string standardName(); Returns the timezone name if not daylight saving time is in effect. static std::string dstName(); Returns the timezone name if daylight saving time is in effect. };
