>          Components: sql

> {noformat}
> CURRENT_TIME
> Returns the current time in the session time zone, in a value of datatype TIMESTAMP WITH TIME ZONE.
> CURRENT_TIMESTAMP
> Returns the current date and time in the session time zone, in a value of datatype TIMESTAMP WITH TIME ZONE.
> {noformat}
> # CURRENT_TIME must return {{TIME WITH TIME ZONE}} (not TIMESTAMP)
> # AI3 currently doesn't support TIME WITH TIME ZONE and TIMESTAMP WITH TIME ZONE data types
> -We should fix the documentation and note that currently call to {{CURRENT_TIME}}, {{CURRENT_TIMESTAMP}} is equivalent to call {{LOCALTIME}}, {{LOCALTIMESTAMP}} respectively.-
> The only difference between LOCALTIMESTAMP/LOCALTIME and CURRENT_TIMESTAMP/CURRENT_TIME is  is the return types.
> But currently we return the same types.
> Possible solution:
> # return {{TIMESTAMP WITH LOCAL TIME ZONE}} for {{CURRENT_TIMESTAMP}}
> # remove {{CURRENT_TIME}} as unsupported.
> # fix the documentation accordingly
