enter image description hereI have two dates in Date format.I have used the following code to find the difference between two dates.
extension Date {
/// Returns the amount of years from another date
func years(from date: Date) -> Int {
return Calendar.current.dateComponents([.year], from: date, to: self).year ?? 0
}
/// Returns the amount of months from another date
func months(from date: Date) -> Int {
return Calendar.current.dateComponents([.month], from: date, to: self).month ?? 0
}
/// Returns the amount of weeks from another date
func weeks(from date: Date) -> Int {
return Calendar.current.dateComponents([.weekOfMonth], from: date, to: self).weekOfMonth ?? 0
}
/// Returns the amount of days from another date
func days(from date: Date) -> Int {
return Calendar.current.dateComponents([.day], from: date, to: self).day ?? 0
}
/// Returns the amount of hours from another date
func hours(from date: Date) -> Int {
return Calendar.current.dateComponents([.hour], from: date, to: self).hour ?? 0
}
/// Returns the amount of minutes from another date
func minutes(from date: Date) -> Int {
return Calendar.current.dateComponents([.minute], from: date, to: self).minute ?? 0
}
/// Returns the amount of seconds from another date
func seconds(from date: Date) -> Int {
return Calendar.current.dateComponents([.second], from: date, to: self).second ?? 0
}
/// Returns the a custom time interval description from another date
func offset(from date: Date) -> String {
if years(from: date) > 0 { return "\(years(from: date))y" }
if months(from: date) > 0 { return "\(months(from: date))M" }
if weeks(from: date) > 0 { return "\(weeks(from: date))w" }
if days(from: date) > 0 { return "\(days(from: date))d" }
if hours(from: date) > 0 { return "\(hours(from: date))h" }
if minutes(from: date) > 0 { return "\(minutes(from: date))m" }
if seconds(from: date) > 0 { return "\(seconds(from: date))s" }
return ""
}
func offsetLong(from date: Date) -> String {
if years(from: date) > 0 { return years(from: date) > 1 ? "\(years(from: date)) yrs ago" : "\(years(from: date)) yr ago" }
if months(from: date) > 0 { return months(from: date) > 1 ? "\(months(from: date)) mo ago" : "\(months(from: date)) mo ago" }
if weeks(from: date) > 0 { return weeks(from: date) > 1 ? "\(weeks(from: date)) wks ago" : "\(weeks(from: date)) wk ago" }
if days(from: date) > 0 { return days(from: date) > 1 ? "\(days(from: date)) days ago" : "\(days(from: date)) day ago" }
if hours(from: date) > 0 { return hours(from: date) > 1 ? "\(hours(from: date)) hrs ago" : "\(hours(from: date)) hr ago" }
if minutes(from: date) > 0 { return minutes(from: date) > 1 ? "\(minutes(from: date)) mins ago" : "\(minutes(from: date)) min ago" }
if seconds(from: date) > 0 { return seconds(from: date) > 1 ? "\(seconds(from: date)) secs ago" : "\(seconds(from: date)) sec ago" }
return ""
}
}
I have applied this extension on two dates in EDT timezone and it is as given below:
let dateFormatterGet = DateFormatter()
// dateFormatterGet.timeZone = TimeZone(abbreviation: "UTC")
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateFormatterPrint = DateFormatter()
// dateFormatterPrint.timeZone = TimeZone(abbreviation: "UTC")
dateFormatterPrint.dateFormat = "yyyy-MM-dd HH:mm:ss"
let date1: Date? = dateFormatterGet.date(from: date) as Date?
// print("date1 is",date1)
let now = Date()
let dateFormatterGet1 = DateFormatter()
dateFormatterGet1.timeZone = TimeZone(abbreviation: "EDT")
dateFormatterGet1.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateFormatterPrint1 = DateFormatter()
dateFormatterPrint1.timeZone = TimeZone(abbreviation: "EDT")
dateFormatterPrint1.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dat = dateFormatterPrint1.string(from: now) as String
let date2: Date? = dateFormatterGet1.date(from: dat) as Date?
let timeOffset3 = date2!.offsetLong(from: date1!)
cell2.dateposted.text = timeOffset3
The time offset value is showing till hours, it is not showing in minutes or seconds. Could anyone tell me what is wrong in this conversion?
