Hi @transformer, I'm not sure I understood your problem, but these are prototype function, you can use in any order you want, ex: var dt = new Date(); then dt.addMinutes(45); dt.addHours(4); or even dt.addMinutes(285); or also dt.addMinutes(45).addHours(4); all will work. If you have a question with some code example, for your problem post it here I'll be happy to help you.

| Dec 28, 2017 at 20:51 | comment | added | Transformer | thanks for the response @Jacobi in my case I dont know the hours before hand. For e.g. I am trying to total all the hours worked in a TableCol across the table rows, to show summary hours. While I can iterate the table; I still dont know how to dynamically, fragment the hours & mins. Here you have it as constants, any chance to make it using a variable function | |

Hi @transformer I would do something like this new Date().addHours(4).addMinutes(45); You can call as many as you want, because the methods return "this" which is the current Date Object.

@TheDembinski—what issues are you expecting? Extending built-ins is generally disliked, but I can't see an issue with Date. It would be nice if each major increment would also optionally set its minor increments (as the set* methods do), so addHours optionally took minutes, seconds and milliseconds so you could do date.addHours(3, 30) to add 3 hours and 30 minutes. addYears would take years, months and days, addMonths would take months and days, addMinutes would take minutes, seconds, milliseconds, etc.
