Question

I have a Wpf Browser application coded in C#, the problem is that Date.Time.Now returns the time on the client pc, and is unreliable, how can a obtain the time from my application server or my MSSQL server?

Answer 1

If you are wanting the Servers Current TimeStamp you will need to create a SQL Query and return it to the application that you are using to show on the Client Machine.

you can try DateTime.UtcNow as well or

Look at some of these examples

The following examples use the six SQL Server system functions that return current date and time to return the date, time or both. The values are returned in series; therefore, their fractional seconds might be different.
A. Getting the current system date and time

SELECT 'SYSDATETIME()      ', SYSDATETIME();
SELECT 'SYSDATETIMEOFFSET()', SYSDATETIMEOFFSET();
SELECT 'SYSUTCDATETIME()   ', SYSUTCDATETIME();
SELECT 'CURRENT_TIMESTAMP  ', CURRENT_TIMESTAMP;
SELECT 'GETDATE()          ', GETDATE();
SELECT 'GETUTCDATE()       ', GETUTCDATE();
/* Returned:
SYSDATETIME()            2007-05-03 18:34:11.9351421
SYSDATETIMEOFFSET()      2007-05-03 18:34:11.9351421 -07:00
SYSUTCDATETIME()         2007-05-04 01:34:11.9351421
CURRENT_TIMESTAMP        2007-05-03 18:34:11.933
GETDATE()                2007-05-03 18:34:11.933
GETUTCDATE()             2007-05-04 01:34:11.933
*/

B. Getting the current system date

SELECT 'SYSDATETIME()      ', CONVERT (date, SYSDATETIME());
SELECT 'SYSDATETIMEOFFSET()', CONVERT (date, SYSDATETIMEOFFSET());
SELECT 'SYSUTCDATETIME()   ', CONVERT (date, SYSUTCDATETIME());
SELECT 'CURRENT_TIMESTAMP  ', CONVERT (date, CURRENT_TIMESTAMP);
SELECT 'GETDATE()          ', CONVERT (date, GETDATE());
SELECT 'GETUTCDATE()       ', CONVERT (date, GETUTCDATE());

/* Returned: 
SYSDATETIME()            2007-05-03
SYSDATETIMEOFFSET()      2007-05-03
SYSUTCDATETIME()         2007-05-04
CURRENT_TIMESTAMP        2007-05-03
GETDATE()                2007-05-03
GETUTCDATE()             2007-05-04
*/

C. Getting the current system time

SELECT 'SYSDATETIME()      ', CONVERT (time, SYSDATETIME());
SELECT 'SYSDATETIMEOFFSET()', CONVERT (time, SYSDATETIMEOFFSET());
SELECT 'SYSUTCDATETIME()   ', CONVERT (time, SYSUTCDATETIME());
SELECT 'CURRENT_TIMESTAMP  ', CONVERT (time, CURRENT_TIMESTAMP);
SELECT 'GETDATE()          ', CONVERT (time, GETDATE());
SELECT 'GETUTCDATE()       ', CONVERT (time, GETUTCDATE());
/* Returned
SYSDATETIME()            18:25:01.6958841
SYSDATETIMEOFFSET()      18:25:01.6958841
SYSUTCDATETIME()         01:25:01.6958841
CURRENT_TIMESTAMP        18:25:01.6930000
GETDATE()                18:25:01.6930000
GETUTCDATE()             01:25:01.6930000
