stack commented on HBASE-8927:
------------------------------
We could left shift millis in the long and then keep incrementing sequence
number within a millisecond? (more expensive than call to nano).
On CLOCK_MONOTONIC from http://linux.die.net/man/3/clock_gettime, it says
"Clock that cannot be set and represents monotonic time since some unspecified
starting point." which is off-putting but when I print it out it is same as
millis.
Did you see it going backward or out of order on SMP Enis (in spite of
CLOCK_MONOTONIC)? Were you on windows?
> Use nano time instead of mili time everywhere
