What is the reason for 3. Forward the OS clock to 3 days?

Also, are we talking about this tooltip (in Brave Nightly)?

[GeetaSarvadnya]

@mrose17: As per the test plan brave/brave-core#9616 Brave Talk promo tooltip should be shown to the new users only after forwarding OS date to 3 days ahead. We are talking about the Try it now prompt, sorry for the confusion.

[mrose17]

Fascinating. I am not surprised that messing with the clock causes problems with cryptographic operations. perhaps there is a better way to test this?

[GeetaSarvadnya]

I am not aware of the other ways to test this in a clean profile. @petemill - Any thoughts on this?

[mrose17]

Here are two possibilities:

First,

1. Set the clock back 3 days and then create a new profile.
2. Quit the browser.
3. Set the clock to the current time and start the browser.

Second, create a new profile at the current time. Periodically check to see if the tooltip comes up within the first three days. (Obviously, this is something that will take at least three days to test...)

@mrose17 we just followed the steps mentioned in the slack thread mentioned below, it worked fine we're waiting for confirmation from @petemill
