Error converting FILETIME to DateTimeit should be simple, put FILETIME in a Long conver it in date using the DateTime.FromFileTimeUtc The help even says: Converts the specified Windows file time to an equivalent UTC time. Now why happens this: original filetime 21/02/2006 00:33:29 bytes: 80 C2 E6 AB 6D 36 C6 01 when I convert it I have: 1) 20/02/2006 22:26:19 2) 20/02/2006 22:26:19 Code: Dim ad3 As System.DateTime Dim aLn1 As Long Dim ad1 As System.Runtime.InteropServices.ComTypes.FILETIME ad1.dwHighDateTime = &H1C6366D ad1.dwLowDateTime = &HABE6C280 aLn1 = (CLng(ad1.dwHighDateTime) << 32) + CLng(ad1.dwLowDateTime) ad3 = DateTime.FromFileTimeUtc(aLn1) Debug.Print("1) " & ad3) ad3.ToLocalTime() Debug.Print("2) " & ad3) and even worst if I do: ad3 = CDate("21/02/2006 00:33:29") the Thicks property is equal to: ad3.Ticks &H8C8049591E69280 Long please can anyone help me? Thanks, M. msAvazzi,
What is it what you want to achieve, there are so many methods in datetime that I am not seeing what your goal is. I gues that is the same for others.

Cor,
I have a FILETIME (that I read from a File) and I want to store it in a DateTime variable. And I do agree with you, it has a lot of methods. Unluckily it looks like THEY DON'T WORK (or is not clear how to have them work). If you try the code I've posted you'll see. here is tha MSDN reference: http://msdn.microsoft.com/library/en-us/cpref/html/frlrfSystemDateTimeClassFromFileTimeUtcTopic.asp?frame=true M Show quoteHide quote "Cor Ligthert [MVP]" wrote: > msAvazzi, > > What is it what you want to achieve, there are so many methods in datetime > that I am not seeing what your goal is.

If I understood correctly it should be the function I'm using: ad3 = DateTime.FromFileTimeUtc(aLn1) Or I'm doing something wrong?

For this reason I look forever only on the English language website. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDateTimeClassFromFileTimeUtcTopic.asp This link was already given by msAvazzi, otherwise I would not have know this.

You are right, It means that the English documentation is not up to date but the German one is. I was already disapointed about this breaking change. :-) CorShow quoteHide quote "Herfried K.

You are again right, normally I would have found that as well as first, but now was I using the by the OP supported link. This is of course not good as documentation.

With all those discussions you would not understand it anymore therefore.

you've been very kind. Can you please try this code? because I'm getting mad.... Dim dt As New DateTime(&H1C6366CABE6C280) MessageBox.Show(dt.ToString) ad3 = CDate("21/02/2006 00:33:29") MessageBox.Show(dt.Ticks) I get a meaningless 20/02/0406 22:26:19 (ok this is equal to my code, exactly the same wrong date) while if I use all other programs (i.e. AXE 3) I got: 2006/02/21 00:33:29 that is the right information. the funny thing is that the Ticks of the right date are: ad3.Ticks &H8C8049591E69280 Long So it looks like that "old" ticks are different from new ones!
