It's not some fixed schedule for updates, it can happen in any minute.
Also, if you are mining in Proportional mode and we have long round (more than 1 hour) then next update will be displayed after length of that round + one hour.
There is also one more case when update can be delayed a bit if you are refreshing it less than once per hour, but overall it doesn't really matters. Sometimes meditation can help.
