max_value

const date_time xtd::date_time::max_value

static

Represents the largest possible value of xtd::date_time. This field is read-only.

Remarks

The value of this constant is equivalent to 23:59:59.9999999 UTC, December 31, 9999 in the Gregorian calendar, exactly one 100-nanosecond tick before 00:00:00 UTC, January 1, 10000.

Examples

The following example instantiates a xtd::date_time object by passing its constructor an xtd::ticks value that represents a number of ticks. Before invoking the constructor, the example ensures that this value is greater than or equal to date_time::min_value.ticks() and less than or equal to date_time::max_value.ticks(). If not, it throws an xtd::argument_out_of_range_exception.

#include <xtd/console>
#include <xtd/date_time>
#include <xtd/int64_object>
#include <xtd/startup>
 
using namespace xtd;
 
class program {
public:
  static auto main() {
    // Attempt to assign an out-of-range value to a date_time constructor.
    auto number_of_ticks = int64_object::max_value;
    auto valid_date = date_time {};
    
    // Validate the value.
    if (number_of_ticks >= date_time::min_value.ticks() && number_of_ticks <= date_time::max_value.ticks()) {
      valid_date = date_time(number_of_ticks);
      console::write_line("{0} is valid.", valid_date.ticks());
    } else if (number_of_ticks < date_time::min_value.ticks())
      console::write_line("{0} is less than {1} ticks.", number_of_ticks, date_time::min_value.ticks());
    else
      console::write_line("{0} is greater than {1} ticks.", number_of_ticks, date_time::max_value.ticks());
  }
};
 
startup_(program::main);
 
// This code produces the following output :
//
// 9223372036854775807 is greater than 3155378975999999999 ticks.
