Function SysTime.opBinary

Gives the result of adding or subtracting a Duration from this SysTime.

SysTime opBinary(string op) (
  Duration duration
) const pure nothrow scope @safe
if (op == "+" || op == "-");

The legal types of arithmetic for SysTime using this operator are

SysTime + Duration --> SysTime
SysTime - Duration --> SysTime

Example

import core.time : hours, seconds;
import std.datetime.date : DateTime;

assert(SysTime(DateTime(2015, 12, 31, 23, 59, 59)) + seconds(1) ==
       SysTime(DateTime(2016, 1, 1, 0, 0, 0)));

assert(SysTime(DateTime(2015, 12, 31, 23, 59, 59)) + hours(1) ==
       SysTime(DateTime(2016, 1, 1, 0, 59, 59)));

assert(SysTime(DateTime(2016, 1, 1, 0, 0, 0)) - seconds(1) ==
       SysTime(DateTime(2015, 12, 31, 23, 59, 59)));

assert(SysTime(DateTime(2016, 1, 1, 0, 59, 59)) - hours(1) ==
       SysTime(DateTime(2015, 12, 31, 23, 59, 59)));

Function SysTime.opBinary

Gives the difference between two SysTimes.

Duration opBinary(string op) (
  SysTime rhs
) const pure nothrow scope @safe
if (op == "-");

The legal types of arithmetic for SysTime using this operator are

SysTime - SysTime --> duration
