Is there any application which can manipulate time and date for any specific application? If I change date and time of system then browser can't let me access internet. Any help will be appreciated. Thank you

  • No, not that I'm aware of, and why would you need that? –  Sep 06 '17 at 23:26
  • @MichaelBay That's not a helpful comment. Linux is very customizable and it's perfectly possible to do what Mihir wants to do. – UTF-8 Sep 06 '17 at 23:31
  • @UTF-8 It wasn't meant to be helpful in the way you think. First, I'm not aware of any way to it. If you do then perhaps you should post an answer. The help I gave was by questioning the purpose of that. Why? Because I suspect this is another X-Y problem -or- something fishy like an attempt to circumvent some time limited software. –  Sep 06 '17 at 23:37
  • @MichaelBay I'm currently writing my answer. It takes some time because I'm currently doing other stuff as well and I want it to be a good one which teaches OP something as OP seems to be new to Linux. – UTF-8 Sep 06 '17 at 23:39
  • @Mihir I'm sorry. I misread your question. My answer solves a different problem. I deleted it and will write another one which (hopefully) will tackle the problem you actually have. – UTF-8 Sep 06 '17 at 23:55

    @MichaelBay What OP does with the answers he gets here is none of your business. He doesn't need to explain what purpose he's planning to use it for. I don't want to answer such questions each time I ask or buy something, do you? – UTF-8 Sep 06 '17 at 23:59

You can use faketime to tell processes it's a different time.

Install it via:

sudo apt install faketime

Then just run your application like this:

faketime -f '-5d' date

This calls date. So just substitute date with whatever you like.

The example goes 5 days back change that part to whatever you like.

If you want to learn more about how you can use faketime, check out its man page:

man faketime

Note that this only works after you installed it.

If you're curious how to achieve this for an application you launch from the Dash, check out this answer.
