Question

[Please vote to close this – see my last comment.]

Hi,

Something like this:

DateTime.ParseExact("25/12/2008 00:00:00", "dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);

works fine on my development machine but not after deployment (server).

I guess it has to do with some time zone configuration. I have tried:

<%@ ... UICulture="en" Culture="en-US" %> 

with no avail. Any suggestions on a postcard please. Thanks.

Christian

PS: Exception:

String was not recognized as a valid DateTime

PPS: I have updated the question. I actually feed in the time bit. sorry about that!

PPPS:
I have now realised that all this has to do with Excel and oledb. The string 25/12/2008 looks like this “12/25/2008 12:00:00 AM” on the server and like this “25/12/2008 00:00:00” on the developement machine. I adjusted the time zone of the server to UK without avail. What else can I do? Thank and sorry about all this confusion!!!

Something like this

You’d do better posting exactly what failed, and the exact error, rather than “something like” what failed.

I would expect your sample to give a FormatException, since the string you’re converting (“25/12/2008”, no time) does not match the format specified (“dd/MM/yyyy hh:mm:ss”).

Also a bit strange to be using hh rather than HH in your format – hh is a 12-hour clock.

I would expect any of the following to work.

// No time component
DateTime.ParseExact("25/12/2008", "dd/MM/yyyy", new CultureInfo("en-US"));

// Works for hours <=12, result is always AM
DateTime.ParseExact("25/12/2008 11:00:00", "dd/MM/yyyy hh:mm:ss", new CultureInfo("en-US"));

// Works for hours using 24-hour clock
DateTime.ParseExact("25/12/2008 13:00:00", "dd/MM/yyyy HH:mm:ss", new CultureInfo("en-US"));
