can I set a value in redis from the redis server's current system time? -

That is, I'd like to add something to a sorted set:

"set1" - & Gt; [1371772258, 1371772265, 1371772299, etc.]

But I do not want to send time values ​​to my server. I want to receive a consistent timestamp from a server clock, running on the server again.

You just use (available with Redis 2.6). It gives two values: the number of ages and microscopic seconds in seconds.

You can call it directly from the application. In that case, 2 roundtrips will be required (to execute at one time, to update one to the zacetre)
