Question

I have a record that I write out to a CSV file using FileHelpers. I want the DateTime fields of the structure to be written out as the UTC date. I currently have the following formatter:

[FieldConverter(ConverterKind.Date, "yyyy-MM-dd")]   

What do I need to do to get it to output the UTC date?

Answer 1

The doc says :

You can check all the supported format
strings check the MSDN docs for
DateTime.ParseExact

So according to : http://msdn.microsoft.com/en-us/library/az4se3k1.aspx

[FieldConverter(ConverterKind.Date, “u”)]

“u” => “yyyy’-‘MM’-‘dd HH’:’mm’:’ss’Z'”
It doesn’t convert the date to utc, just format it

You still need DateTime.ToUniversalTime to convert it.

Edit
If you have something like :

[FieldConverter(ConverterKind.Date, "ddMMyyyy" )]
public DateTime ShippedDate;

Then add a temp ShippedDateUTC :

public DateTime ShippedDate;

[FieldConverter(ConverterKind.Date, "ddMMyyyy" )]
public DateTime ShippedDateUTC {
  get{ return ShippedDate.ToUniversalTime();}
}
