DateTime.ToString("R")

[Marc Gravell]

Just been debugging a daylight savings glitch... something that
interested me:

(in a BST locale at 5:14 local time, 4:14 GMT)

DateTime.Now.ToString("R") >> "Mon, 26 Mar 2007 05:14:34 GMT"

However...
DateTime.Now.IsDaylightSavingTime() >> true

DateTime.UtcNow.ToString("R") >> "Mon, 26 Mar 2007 04:17:04 GMT"

Doesn't that make the DateTime.Now.ToString("R") incorrect by RFC822?
Shouldn't it be using local offset?

Anyways... fixed using UTC formats ;-p

RTFM to myself:

<q>Formatting does not modify the value of the DateTime object that is
being formatted. Therefore, the application must convert the value to
Coordinated Universal Time (UTC) before using this format specifier.</
