How to clear csrf cookie?

[eluser]Unknown[/eluser]
I have my wamp server setup in my localhost. For some testing, i changed my computer time from Aug 23 to Sept X then switching back to Aug 23. Now i'm unable to submit any forms in the website unless i changed to Sept or use other browsers(firefox).

If only works if i turn off the csrf.

Any idea how to clear this?

*I have tried clear browsing data(Google Chrome) but no luck
