NEW_TIME
Syntax
Purpose
NEW_TIME
returns the date and time in time zone timezone2
when date and time in time zone timezone1
are date
. Before using this function, you must set the NLS_DATE_FORMAT
parameter to display 24-hour time. The return type is always DATE
, regardless of the data type of date
.
Note:
This function takes as input only a limited number of time zones. You can have access to a much greater number of time zones by combining the FROM_TZ
function and the datetime expression. See FROM_TZ and the example for "Datetime Expressions".
The arguments timezone1
and timezone2
can be any of these text strings:
-
AST, ADT: Atlantic Standard or Daylight Time
-
BST, BDT: Bering Standard or Daylight Time
-
CST, CDT: Central Standard or Daylight Time
-
EST, EDT: Eastern Standard or Daylight Time
-
GMT: Greenwich Mean Time
-
HST, HDT: Alaska-Hawaii Standard Time or Daylight Time.
-
MST, MDT: Mountain Standard or Daylight Time
-
NST: Newfoundland Standard Time
-
PST, PDT: Pacific Standard or Daylight Time
-
YST, YDT: Yukon Standard or Daylight Time
Examples
The following example returns an Atlantic Standard time, given the Pacific Standard time equivalent:
ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS'; SELECT NEW_TIME(TO_DATE('11-10-09 01:23:45', 'MM-DD-YY HH24:MI:SS'), 'AST', 'PST') "New Date and Time" FROM DUAL; New Date and Time -------------------- 09-NOV-2009 21:23:45
