Mixing
Easy way to get a readable date from a long (timestamp) in scala
1
My question is simple
If I do:
var start = System.currentTimeMillis
I get:
start: Long = 1542717303659
How should I do to get a string looking to something readable for a human eye?:
ex: "20/11/2018 13:30:10"

You can use the java.time library like:
val formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm:ss")
formatter.format(LocalDateTime.now)
If you only have the timestamp, this solution gets a bit more complex:
formatter.format(LocalDateTime.ofInstant(Instant.ofEpochMilli(System.currentTimeMillis()), ZoneId.of("UTC")))
Then I would take java.text.SimpleDateFormat :
new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(System.currentTimeMillis())
To get back to the Timestamp:
new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse( "02/12/2012 12:23:44" ).getTime

Don't overthink it: nothing wrong with just new Date(start).toString

Did you try it? :) (it gives you time too). But if all you need is evaluate what the script took, you are probably better off withLongto begin with. Just subtract start from the end, and you get the number of milliseconds.

You can use java.time library and get it in readable format as below one-liner.
scala> java.time.LocalDateTime.ofEpochSecond(System.currentTimeMillis/1000,0,java.time.ZoneOffset.UTC)
res31: java.time.LocalDateTime = 2018-11-21T18:37:49
scala>
I'm just diving the Milliseconds by 1000, so that we get EpochSecond.
For getting it back,
scala> java.time.LocalDateTime.parse("2018-11-21T18:41:29").toEpochSecond(java.time.ZoneOffset.UTC)
res40: Long = 1542825689
scala>

You can use java.time library and get it in readable format as below one-liner.
scala> java.time.LocalDateTime.ofEpochSecond(System.currentTimeMillis/1000,0,java.time.ZoneOffset.UTC)
res31: java.time.LocalDateTime = 2018-11-21T18:37:49
scala>
I'm just diving the Milliseconds by 1000, so that we get EpochSecond.
For getting it back,
scala> java.time.LocalDateTime.parse("2018-11-21T18:41:29").toEpochSecond(java.time.ZoneOffset.UTC)
res40: Long = 1542825689
