Detailed Description

Class for management of date and time information.

Class for management of date and time information. It includes arithmetics and comparisons operations.

Example : creating a date

  openfluid::core::DateTime aDate(2009,01,25,12,05,00);

Example : adding time span to a date

  // adding 45 seconds
  aDate.addSeconds(45);

  // adding 5 minutes
  aDate.addSeconds(openfluid::core::DateTime::Minutes(5));

  // adding an hour
  aDate.addSeconds(openfluid::core::DateTime::Hour());

  // adding 60 days
  aDate.addSeconds(openfluid::core::DateTime::Days(60));

Example : subtracting time span to a date

  // subtracting 10 seconds
  aDate.subtractSeconds(10);

  // subtracting 30 days
  aDate.subtractSeconds(openfluid::core::DateTime::Days(30));

Example : getting difference in seconds between two dates

  openfluid::core::DateTime FirstDate(2009,01,25,12,05,00);
  openfluid::core::DateTime SecondDate(2009,02,28,00,00,00);

  openfluid::core::rawtime_t Diff;

  Diff = SecondDate - FirstDate;

  if (Diff > openfluid::core::DateTime::Days(60))
    std::cout << "The difference between the two dates is greater than 60 days" << std::end;
  else
    std::cout << "The difference between the two dates is lesser than 60 days" << std::end;
