If two different drill bits have different time zone, will this line get different value of DateTime?  

Let's say getQueryStartTime() return 10000 milliseconds.  

Bit 1 : UTC-8:00
BIT2 : UTC.
Then, Bit1 will have 10000 miliseconds in UTC-8:00, and Bit2 will have 10000 millseconds in UTC. 

Is this the expected result? 

Similiar issue for current_date.
