The time attribute of selector



I am going to show the max selector time attribute and follow to get the syntax and run it in influxDB v1.2.0. However it throws exception:

> select max(water_level), max(water_level)::time from h2o_feet where time > 1439856000000000000 and time < 1439859240000000000
ERR: error parsing query: found ::, expected FROM at line 1, char 42

I notice the issue is closed in 1.0.0 version, so InfluxDB v1.2.0 contains such feature? If yes, what InfluxQL should I write to get the time attribute? Thanks!
