Yu Qing commented on TS-2079:
-----------------------------
I think the CAS is useless on the modern CPU, we can use ink_get_hrtime() to
get the current time directly.
> Replace ink_cluster_time() with just "localtime"

> I think this shared "adjustment" of a time concept across a cluster is
> generally pointless these days. What it does it to take a negative approach,
> and use the largest skew as an offset on each box. This is to e.g. allow for
> cluster cache object to live at a duration based on the fastest clock.
> It's possible this was a useful feature in the past, but honestly, with NTP
> being ubiquitous, I think we should just assume that the clocks are within
> reasonable skew inside the cluster.
