    7 years of .NET experience and you don't see what's wrong with it? Or is there a joke in there that I'm missing? (Monday morning, brain not fully engaged yet)

      Actually DateTime date = DateTime.Parse(DateTime.Now.Date.ToString("dd/MM/yyyy")); can be written as DateTime date = DateTime.Now.Date; No strings involved! You'll also notice that the original coder acutally had the "DateTime.Now.Date" bit, which they then cast to a string (in UK date format) that is subsequently parsed back to a DateTime.

      In some parts of the world the original statement and yours will not yield the same result. And the original may throw an exception, yours wouldn't. So we need to see the specs first. :)

        I've inherited one of the worst code-bases I've ever seen in 9 years of .netting. I've spotted this little gem scattered like gingerbread-crumbs thoughout the code:

        DateTime date = DateTime.Parse(DateTime.Now.Date.ToString("dd/MM/yyyy"));

        To make it worse this code is repeated not just in different classes but in the same class :wtf: To add piquancy, the variable being set is just called date, not today or todaysDate or something bit more sensible, so I had to work out what it did. I still can't work out why, I only know it makes my eyes bleed....

                For a moment there I thought you were measuring your licence expiry in ticks. "This evaluation licence will expire in 342,827,400 nanoseconds."

                              Not good but I've seen worse. I'm sitting in front of code that's full of... try { // various code here } catch { } finally { } Empty catch and finally blocks everywhere. In your case though I think that will break if regional language settings define the date format as anything other than date/month/year as it'll format it with the date first and then reparse it as say mm/dd/yyyy in the US causing the date and month to be swapped.

                                One thing it will do is break if you run it in America. If the date is 5th March 2009, the ToString conversion will give you 05/03/2009. But because no format is specified on the Parse method, it will assume the default date format, which in America is MM/dd/yyyy. So 05/03/2009 will get converted to 3rd May 2009. My guess would be this is someone from a Java background because java.util.Date doesn't have an equivalent to .NET's DateTime.Date property, and it's not so easy to strip off the time part. The correct way to do it in Java is with java.util.Calendar, but lots of people use this sort of clumsy format/parse approach.

                                Actually you're dead wrong in so many ways. :D 1) Since ToString() and Parse() both use the *same* culture, it doesn't matter what that culture is. 2) The culture used is not necessarily the system default. It is the current culture, which can be set programmatically to whatever we'd like it to be. 3) The default culture doesn't actually depend on where the machine is located. I once wrote a disposable class called CultureBubble in order to easily run portions of code with a specific culture, like this:

                                using (new CultureBubble("FR"))
                                {
                                foo();
                                bar();
                                }

                                This technique is quite useful, as it requires minimal coding compared to writing logic for dealing with different cultures everywhere data is parsed or presented in culture-dependent ways.
