I changed my time zone on Adsense from the default to London. Unfortunately, due to this, i have seen a drastic fall in daily earnings on my account. For this reason, i intend to revert my time zone setting back to default. The issue now is that i don't know the default time zone. Can some help out?
Well it shouldn't, I set mine to London time also with no problems. The default time is "(-7:00) Pacific Time" if you really need to change back though.
Yes, changing timezone will not affect your earnings. The default time of adsense is CA time. Can I ask where are your visitors coming from?
I should say timing doesn't affect your earning it just starts calculating based on the time specified by you. So for example if you set your time to GMT then it will show the EOD calculation by 00:00 GMT and so on. If you still like to change it to default time then follow the time mentioned above by Myshufflemix i.e. PDT
