Noda: Find out if in daylight saving

Question

How do I find out if my current local time is adjusted by Daylight Savings or not. Basically the equivalent of DateTime.Now.IsDaylightSavingTime() in NodaTime

I saw this, but could not make the translation to Noda...

Lasse's answer is correct, but it can be made simpler:

From v1.3 you can use ZonedDateTime.IsDaylightSavingTime:

var zone = ...;
var now = ..;
var daylight = now.InZone(zone).IsDaylightSavingTime();

And from v2.0 (unreleased at the time of writing) you can use ZonedClock to make the original conversion even simpler:

var now = zonedClock.GetCurrentZonedDateTime();
var daylight = now.IsDaylightSavingTime();

@MalcolmRowe: Ooh, thanks. I'd thought I'd only added it in 2.0 :) – Jon Skeet Jul 30 '14 at 08:16

You can try this:

var localTimeZone = DateTimeZoneProviders.Tzdb.GetSystemDefault();
var now = SystemClock.Instance.Now;
var interval = localTimeZone.GetZoneInterval(now);
// inspect interval.Savings

Thanks. This did it: var isDLS = DateTimeZoneProviders.Tzdb.GetSystemDefault().GetZoneInterval(SystemClock.Instance.Now).Savings.Ticks!=0 – Nestor Jul 29 '14 at 09:44
