Server-assigned timestamps aren't noticeably slower than user-assigned 
timestamps, if that's what you're referring to WRT throughput.

As for using currentTimeMillis(), probably fine, but not always.

1) NTP updates might cause currentTimeMillis() to change in reverse
2) You need to make sure the delete and update always come from the same 
host (otherwise two hosts might have different values for 

Time is hard in distributed systems.
