How to convert date string to timestamp in Kotlin?

Question

I want to convert a date string to unix timestamp from a date string e.g. 14-02-2018

Can someone help?

Answer 1

use this to convert the date string to UNIX timestamp

val date = SimpleDateFormat("dd-MM-yyyy").parse("14-02-2018") println(date.time) 

Answer 2

Since JDK 8 you can do:

val l = LocalDate.parse("14-02-2018", DateTimeFormatter.ofPattern("dd-MM-yyyy"))  val unix = l.atStartOfDay(ZoneId.systemDefault()).toInstant().epochSecond 

Note that the example uses your system's default timezone.
