> When users use a PROCTIME() in SQL, the return value of PROCTIME() has a
> timezone offset with the wall-clock time in users' local time zone, users
> need to add their local time zone offset manually to get expected local
> timestamp(e.g: Users in Germany need to +1h to get expected local timestamp).
> This issue to correct PROCTIME() function
> |*function*|*existed problem*|*current behavior*|*proposed changes*|
> |PROCTIME()|returns UTC timestamp, but user expects current timestamp in
> session time zone|return type: TIMESTAMP *PROCTIME*
> #session timezone: UTC
> 2020-12-28 23:52:52
> #session timezone: UTC+8
> 2020-12-28 23:52:52|return current timestamp in session time zone for
> PROCTIME(), the return type should be *TIMESTAMP WITH LOCAL TIME ZONE
> *PROCTIME**
> #session timezone: UTC
> 2020-12-28 23:52:52
> #session timezone: UTC+8
