Sorry for the delay, had to drop my wife to work.
For the 3 block sets mentioned (490157-490158, 490619-490620, and 490750-490751)
There are 3 things that i have determined
- At that time the “ComputeNextStakeModifier” is also calculated
- the timestamp of date= in the SetBestChain is off by a margin (1 hour) between blocks
- ‘progress=’ is larger than normal
refer to the following log entries
My suspicion is that a client has the wrong system time set that is discovering the block
(i havent looked to deep into source to see where that value is set but seems to be associated with the block)
[EDIT] I did look into the source-code just now, and if i am correct the time associated with discovering block is inserted by the client for that block.
Therefore if the client time is wrong, then it could have an effect
Thankfully it looks like there is a correction also made for the following blocks
The progress value looks like it is a time adjustment ± to help with staking time
in each case the progress value is much higher than other values around that time
