Constructing date from Int the right way

Question

So i get from the backend this answer :

{ "SERVERDateTimeGet": { "Return Code" : 0,
    "Return String" : "No Error",
    "Year" : 2018,
        "Month" : 8,
        "Day" : 29,
        "Hour" : 14,
        "Minute" : 16,
        "Second" : 20,
        "Daylight" : 1,
        "NTP" : 0,
        "NtpDhcp" : 0,
        "NtpServers" : "time.google.com",
        "Timezone" : "EET-2EEST,M3.5.6/0:01,M9.1.5" }
 }

(I know this is bad ,very bad but for the time that is what i get)

I have this method :

func makeDate(year: Int, month: Int, day: Int, hr: Int, min: Int, sec: Int) -> Date {
    let calendar = Calendar(identifier: .gregorian)
   // calendar.timeZone = TimeZone.current
    let components = DateComponents(year: year, month: month, day: day, hour: hr, minute: min, second: sec)
    //let components = DateComponents(timeZone: TimeZone.current, year: year, month: month, day: day, hour: hr, minute: min, second: sec)
    return calendar.date(from: components)!
}

but when i get the date it is 3 hours back. I assume that this is because the time zone , but as you can see i am not using the time zone. Is there any other way to build date or just use the current ints?

What do you mean by "the date is 3 hours back"? How did you find out the difference of 3 hours? Please edit the question and provide the `makeDate` call with parameters — Andreas Oetjen, Aug 30 '18 at 07:30
Your code works perfectly fine on the playgrounds. Check your input to the method. — Rakesha Shastri, Aug 30 '18 at 07:31
If you don't set TimeZone, that means your time will be in UTC, so you have -3 hours gap. To get the right value you need configure TimeZone. You can check it here https://stackoverflow.com/questions/1862905/nsdate-convert-date-to-gmt — gaRik, Aug 30 '18 at 07:51
@gaRik thanks, you were right. i just needed to make it local time. do you want to write that as an answer? — ironRoei, Aug 30 '18 at 08:03
Do you not want to use a time zone or do you not know which time zone to use? — Willeke, Aug 30 '18 at 15:08

That explained why i always got it 3 hour back. i did that method from the link you gave: func toLocalTime() -> Date { let timezone = TimeZone.current let seconds = TimeInterval(timezone.secondsFromGMT(for: self)) return Date(timeInterval: seconds, since: self) } works like a charm:) thanks! – ironRoei Aug 30 '18 at 08:08
