Hi All,

Assume we have two time stamp like:    9/15/2002  8:05   and    9/15/2002
9:05

if we need to evaluate the difference of these two time stamp in terms of
hours ( or minutes ), how to do that?

Hive seems only support the format  'yyyy-MM-dd HH:mm:ss' , how can we
transform the two time stamps into the format that can be processed by
hive?

thanks for any suggestion in advance.

Could convert them to unix time which will give you two bigints that you
can subtract to get seconds, and divide result by 60 to get minutes, etc.

Hi, also take a look at Hive date functions:
