Often we encounter problem in converting and storing the correct date time in databases. The major problem comes when we have a web site for specific country or open to all the world and our Server location is somewhere else and storing the data according to the user or client location becomes very difficult.
Below are some most commonly used Time Zones which can be made use of so that it can be kept in the logic while storing the data correctly according to the time zone.
–UTC Time
SELECT ’UTC Time’ as ’TimeZone’,'UTC’ as ’TimeAbb’ ,CONVERT(varchar(20),GETUTCDATE(),113) as ’Current Time’
UNION ALL
–IST Time i.e. India Time=UTC+5:30
SELECT ’India Time’ as ’TimeZone’,'IST’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(MI,30,DATEADD(hh,5,GETUTCDATE())),113) as ’Current Time’
UNION ALL
– Atlantic Time = UTC-4
SELECT ’Atlantic Time’ as ’TimeZone’,'ATS’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(hh,-4,GETUTCDATE()),113) as ’Current Time’
UNION ALL
– Eastern Time = UTC-5
SELECT ’Eastern Time’ as ’TimeZone’,'ETS’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(hh,-5,GETUTCDATE()),113) as ’Current Time’
UNION ALL
– Mountain Time = UTC-6
SELECT ’Mountain Time’ as ’TimeZone’,'MTS’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(hh,-6,GETUTCDATE()),113) as ’Current Time’
UNION ALL
– Pacific Time = UTC-8
SELECT ’Pacific Time’ as ’TimeZone’,'PST’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(hh,-8,GETUTCDATE()),113) as ’Current Time’
UNION ALL
– Alaska Time = UTC-9
SELECT ’Alaska Time’ as ’TimeZone’,'AKST’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(hh,-9,GETUTCDATE()),113) as ’Current Time’
UNION ALL
– Hawai Time = UTC-10
SELECT ’Hawai Time’ as ’TimeZone’,'HST’ as ’TimeAbb’,CONVERT(varchar(20),DATEADD(hh,-10,GETUTCDATE()),113) as ’Current Time’
Output
- Display all time Zones
