Does the sync time limit between servers have anything to do with Zookeeper's timeliness guarantee?

Hi folks,

The consistency guarantees section of Zookeeper's doc mentioned that the
clients view of the system is guaranteed to be up-to-date within a certain
time period. What that period is specified is not mentioned, however.

Can it be taken to be syncLimit * tickTime in the configurations? e.g. if
syncLimit * tickTime in a cluster is 10000ms... can I say...

if client A set node Q's value from 0 to 1, and nobody did anything to node
Q after that, then
client B is guaranteed to read node Q's value as 1 after 10 seconds?

Best Regards,
Martin Kou
