Timestamp in Swift

I am determining the current time in swift with this code

let currentDate = Date().timeIntervalSince1970 * 1000

the result looks like 

1493199752604.24

The obtained value is in milliseconds right? What is the . inside the value?

I need to determine if the difference between two such date is equal or greater than 2 hours. 

if (currentDate - oldDate >= 7200000){
// do something
}

is this code correct?

Yes it is working fine. Checkout this example for difference greater than 2 hours

let currentDate = Date().timeIntervalSince1970*1000
let calendar = NSCalendar.current
let yesteraysDate = calendar.date(byAdding: .day, value: -1, to: Date())
let oldDate = yesteraysDate!.timeIntervalSince1970*1000
if (currentDate - oldDate >= 7200000){
    print("greater or equal than two hour")  //"greater or equal than two hour"
} else {
    print("smaller than two hour")
}

if difference is less than 2 hours

let currentDate = Date().timeIntervalSince1970*1000
let calendar = NSCalendar.current
let yesteraysDate = calendar.date(byAdding: .hour, value: -1, to: Date())
let oldDate = yesteraysDate!.timeIntervalSince1970*1000
if (currentDate - oldDate >= 7200000){
    print("greater or equal than two hour")  
} else {
    print("smaller than two hour")  //"smaller than two hour""
}

Try to use more benefits from Swift. Try to fetch difference in hours with usage of dateComponents.

let calendar = NSCalendar.current

let hours = calendar.dateComponents([.hour], from: Date(), to: Date())
