I like those built-in php date expressions like  1 hour  but for some reason  they fall out of my head all of the time  Besides  none of the IDEs I m aware of suggest auto-completion facility for that kind of stuff  And  finally  although juggling with those strtotime and date functions is no rocket science  I have to google their usage each time I need them   That s why I like the solution that eliminates  at least mitigates  those issues  Here s how adding x hours to a date can look like    new Future      new DateTimeFromISO8601String  2014-11-21T06 04 31 321987 00 00        new NHours  x         - gt value      As a nice bonus  you don t have to worry about formatting the resulting value  it s already is ISO8601 format   This example uses meringue library  you can check out more examples here
