Do you mean "What time is it best to click for ads / do Tasks / do Offers?"
I'm not from Qatar, but it's a good thing to keep tabs with a secondary clock, one that can tell you on EST ( Eastern Standard Time ) -- here's a small tip how to set two clocks on your desktop / laptop on any Windows OS: Local Time for posts made on the Forum | ClixSense Forum
Well, if it's time, as in real time, that would depend -- everything from ads, Tasks, Offers -- are completely random; they appear as they come, and it's just up to the user if they'd be there. Ads, regardless of value, will come as advertisers offer it -- and that means, it'll come; this comes as well with Offers
Tasks on the other hand, which is handled by CrowdFlower, is somewhat different -- ClixSense just provides the means to host it; while distribution, price per Tasks and it's number of availability is all CrowdFlower's control
So, if you need to know what's the best time to get the opportunities to earn?
Well, anytime is a good time
