Function Documentation

ssfJulianDate JulianDate (  const ssfSeconds &  _time  )  [related, inherited]

Calculates the Julian Date given a time in seconds since the system epoch. This function takes in seconds since epoch and returns the datetime in Julian Date format. Since the input time is seconds since system epoch (Jan 1, 1970 at midnight for linux), the JulianDate function uses the system gmtime() function to convert to a DateTime struct. Warning: be careful of differences in system epoch times (Unix vs. Windows). Parameters: _time  The time to be converted in seconds since the system epoch time. Returns: this function returns the conversion from seconds since system epoch time to Julian Date. Definition at line 31 of file Time.cpp. References O_SESSAME::ssfJulianDate. Referenced by O_SESSAME::ssfTime::GetEpochJulianDate(), O_SESSAME::ssfTime::GetJulianDate(), O_SESSAME::ssfTime::SetEpochJulianDate(), and O_SESSAME::ssfTime::SetJulianDate().

Variable Documentation

ssfTime O_SESSAME::tickTime(-1) [static]

Initializes the tick/tock counter. Used for calculating the time during operations. First tick() is called, then when the operation has been completed tock() is called which returns the time (in seconds) since tick() was called. See also: tock() tick(); for (int ii = 0; ii < 10; ++ii) { ii += ii*ii; } cout << tock(); the sample code would output the time it took to calculate to the console. Referenced by O_SESSAME::tick().
