DateFormatter sets AM/PM by default

Question

I'm trying to convert the current time and date to a timestamp format. Since the service is receiving this format for timestamps:

2018-26-11T11:38:00Z

I decided to use a format like this:

yyyy-M-dd'T'H:mm:ss'Z'

But, when I use a date formatter to convert it, I'm getting an unwanted AM/PM tag at the end by default:

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-M-dd'T'H:mm:ss'Z'"
let currentTimeAndDate = Date()
let timeStamp = dateFormatter.string(from: currentTimeAndDate)
// Prints "2018-12-05T12:58:38 PMZ"

How can I remove that AM/PM by default at the end of the string?

Answer 1

• Set the locale to fixed en_US_POSIX"

  dateFormatter.locale = Locale(identifier: "en_US_POSIX")
  

• Or use the dedicated ISO8601 formatter

  let dateFormatter = ISO8601DateFormatter()
  let currentTimeAndDate = Date()
  let timeStamp = dateFormatter.string(from: currentTimeAndDate)
