Easiest way to convert GMT date to DateTime object

Question

I am getting GMT DateTime as string input. For example

SampleDate = "20170221T085258.732 GMT"

Now, I want to convert this to datetime object. What is the best way of doing this conversion?

You just need to use ToLocalTime() Then you can change it to whatever timezone you care about.

 DateTimeOffset.Parse(SampleDate).ToLocalTime();

*I am getting GMT DateTime as string input* - `SampleDate` is a string, not a `DateTime` type – Ňɏssa Pøngjǣrdenlarp May 12 '17 at 18:34
sorry, spoke to fast, use datetimeoffset first, then you can do localtime to get it to your timezone if you need to. – chris-crush-code May 12 '17 at 18:36
I tried this earlier, getting "String was not recognized as a valid DateTime". Did I miss something ? – Tanmay May 12 '17 at 18:45

var offset = new Date().getTimezoneOffset();

To remove the GMT and time zone, change the following line:

document.write(d.toString().replace(/GMT.*/g,""));

Hi try this code using DateTime.ParseExact()

 string SampleDate=""20170221T085258.732 GMT";  
 DateTime dateObject = DateTime.ParseExact(SampleDate,"ddd MMM dd yyyy HH:mm:ss 'GMT'zzz",  System.Globalization.CultureInfo.InvariantCulture);

For more info heres the link for DateTime.ParseExact MSDN: https://msdn.microsoft.com/en-us/library/w2sa9yss(v=vs.110).aspx

Below code worked for me. Date contain some unwanted characters like "T",".","GMT" , once I removed those, it started working..

But I feel that, there has to be some better solution for this.

    //I can write a regular expression to keep only numeric values and avoid this replacements...
    SampleDate = "20170221T085258.732 GMT"
    SampleDate = SampleDate.Replace("GMT", "")
    SampleDate = SampleDate.Replace("T", "")
    SampleDate = SampleDate.Replace(".", "")

    Dim dateObject As DateTime = DateTime.ParseExact(SampleDate.Trim(), "yyyyMMddHHmmssfff", System.Globalization.CultureInfo.InvariantCulture)

You should edit your question to include this information and then delete this answer. If you do this, there is a chance that the question may be re-opened, but I suspect that it will be marked as a duplicate. Also, your conversion will only be accurate if the computer executing the code is configured as being in the GMT timezone. – TnTinMn May 13 '17 at 02:21
