Function Documentation

addSeconds()

DateTime openswmm::datetime::addSeconds ( DateTime  date, double  seconds  )

inline

Add seconds to a DateTime — numerically identical to legacy.

Legacy: datetime_addSeconds() in datetime.c

Decomposes time to integer H:M:S, adds seconds, recomposes. This decompose-recompose cycle is deterministic and produces the exact same floating-point result as the legacy engine.

Here is the call graph for this function:

Here is the caller graph for this function:

dayOfYear()

int openswmm::datetime::dayOfYear ( DateTime  date )

inline

Get day of year (1..365/366) from DateTime.

Here is the caller graph for this function:

decodeDate()

void openswmm::datetime::decodeDate ( DateTime  date, int &  year, int &  month, int &  day  )

inline

Decode DateTime to year-month-day.

Here is the caller graph for this function:

decodeTime()

void openswmm::datetime::decodeTime ( DateTime  time, int &  h, int &  m, int &  s  )

inline

Decode DateTime to hour:minute:second.

Legacy: datetime_decodeTime() in datetime.c

Uses floor(fracDay + 0.5) for rounding, matching legacy exactly. This integer decomposition is the key to deterministic date arithmetic.

divMod()

void openswmm::datetime::divMod ( int  n, int  d, int *  result, int *  remainder  )

inline

Integer divmod — matching legacy divMod().

Here is the caller graph for this function:

encodeDate()

DateTime openswmm::datetime::encodeDate ( int  year, int  month, int  day  )

inline

Encode year-month-day to DateTime.

encodeTime()

DateTime openswmm::datetime::encodeTime ( int  hour, int  minute, int  second  )

inline

Encode hour:minute:second to fractional day.

Here is the caller graph for this function:

isLeapYear()

bool openswmm::datetime::isLeapYear ( int  year )

inline

Check if year is a leap year.
