TimeZoneInfo doesn't find time zones on Unity

Unity Engine

Why TimeZoneInfo (found in system namespace) doesn’t find time zones on Unity? Doesn’t mono support it? I’m using Windows.
The following code prints only 0:

using UnityEngine;
using System.Collections;
using System;
using System.Collections.ObjectModel;
public class Timezones : MonoBehaviour {

    // Use this for initialization
    void Start () {
        Debug.Log(TimeZoneInfo.GetSystemTimeZones().Count);
        foreach (TimeZoneInfo z in TimeZoneInfo.GetSystemTimeZones())
            Debug.Log(z.Id);
        ReadOnlyCollection<TimeZoneInfo> tzCollection;
        tzCollection = TimeZoneInfo.GetSystemTimeZones();
        foreach (TimeZoneInfo timeZone in tzCollection){
            print(timeZone.Id+":"+ timeZone.DisplayName);
        }
    }

}

might work

I couldn’t find timeZoneInfo class from mono compatibility page, so I guess it’s not compatible with Unity. I don’t need local currenttimezone, i need to get any timezone from TimeZoneInfo.
