Parse into a DateTimeOffset
instead, given that you've got an offset. From the documentation of the zz
specifier that you're using:
With DateTime values, the "zz" custom format specifier represents the signed offset of the local operating system's time zone from UTC, measured in hours. It does not reflect the value of an instance's DateTimeKind property. For this reason, the "zz" format specifier is not recommended for use with DateTime values.
So you'd end up with:
DateTimeOffset result;
bool success = DateTimeOffset.TryParseExact
(text, "ddd MMM dd HH:mm:ss 'GMT'zzz yyyy",
CultureInfo.InvariantCulture, DateTimeStyles.None, out result);
From there, you can take the DateTime
part, which will be midnight on September 11th.
If you want just a date, you could use my Noda Time project to create a LocalDate
:
LocalDate = OffsetDateTime.FromDateTimeOffset(result).LocalDateTime.Date;
(I'd love to suggest parsing directly to OffsetDateTime
, but we haven't got support for that yet. We're hoping to include it in version 1.2.)
