As per following discussion:

http://mail-archives.apache.org/mod_mbox/jmeter-user/201502.mbox/%3CCOL129-W48514C5AE7E5933103B5DCAC2C0%40phx.gbl%3E

It appears there is a bug due to rounding which abnormally rounds 2.9.... to 2.

Comment 2 Philippe Mouawad 2015-02-19 22:31:02 UTC 
Note maybe some clarification should be added regarding the rounding problem that when close to 0.5 will create issues.
Or maybe an enhancement to make sleep go up to Nanos.
Comment 3 Philippe Mouawad 2015-03-22 18:16:59 UTC 
Closing as fixed in 2.13.
