*>But If I move the data from EST to Central will the timestamp with
timezone be correct?The correct way to do that is to use the AT TIME ZONE
function.https://www.postgresql.org/docs/9.4/static/functions-datetime.html#FUNCTIONS-DATETIME-ZONECONVERT
<https://www.postgresql.org/docs/9.4/static/functions-datetime.html#FUNCTIONS-DATETIME-ZONECONVERT>*

*eg:*

*postgres=> SELECT TIMESTAMP '2001-02-16 20:38:40' AT TIME ZONE 'EST'
as Eastern,postgres-> TIMESTAMP '2001-02-16 20:38:40' AT TIME
ZONE 'CST' as Central,postgres-> TIMESTAMP '2001-02-16
20:38:40' AT TIME ZONE 'MST' as Mountain,postgres-> TIMESTAMP
'2001-02-16 20:38:40' AT TIME ZONE 'PST' as Pacific; eastern
| central | mountain |
pacific------------------------+------------------------+------------------------+------------------------
2001-02-16 20:38:40-05 | 2001-02-16 21:38:40-05 | 2001-02-16
22:38:40-05 | 2001-02-16 23:38:40-05(1 row)
