"Rolling Time" is a debug output that indicates when Phoenix increments the timestamp on a WorkUnit. This reduces the load on the pool server by generating more work locally instead of asking for more. This will only occur on pool servers which send the X-Roll-NTime header.

First thanx for the explanation.
Now when I know what it means, I found this feature on the website of bitcoin.cz (Slush's Pool) to. He has implemented this feature to his pool.

But maybe there is a problem. Or better to say it seems for me like I have a problem.
With Phoenix 2 I have a higher Hashrate on my system. But I get lower average BTC in the pool for my work on the last 2 days.

The pay out system on bitcoin.cz is in the way that the last shares are more important than the first ones.
Could it be, because of this proportional system and the fact X-Roll-NTime reduces the load on the pool server, that I submit hashes in longer distances? But you will get more BTC on bitcoin.cz when you are close to the moment, when the solution is found.

So this feature seems to be good for the pool, but maybe bad for me Wink

And I have to think about the probability, that I also will get more BTC, when I sometimes will submit more datas close to the end.

But there is one question. Is it possible to disable this feature in the miner? Is there a setting I have to set on false?

Thanks for the help again!

A few things:

1. Measuring payout over a period of 2 days on any non pay-per-share pool is not enough data to make any conclusions. (pool luck makes a big difference)

2. Rolling time doesn't have any effect on sending results. You have the same odds of finding a share either way. (and thus the payout is not affected)

3. The pool doesn't care if a share is from locally generated rolltime work or work sent by the server. Either way it will count the same.

4. If you still want disable the feature you can modify your URL to set maxtime:
