7952 :: Parse unix time

• talaing (orginal) [2021-05-08T17:05:05+02:00] view original

  Hello,

  I'm trying to parse Unix time to HH:MM:ss format. That's how my code looks like:

  import times
  
  let datetime = fromUnix(1623524119)
  echo datetime
  
  let time = parse($datetime, "yyyy-mm-dd HH:MM:ss")
  echo time.format("HH:MM:ss")
  Run

  Here's converted timestamp: 2021-06-12T20:55:19+02:00. When I run the code, this error occurs:

  Error: unhandled exception: Failed to parse '2021-06-12T20:55:19+02:00' with format 'yyyy-mm-dd HH:MM:ss'. Unexpected character: T [TimeParseError]

  As you can see, there's unexpected T character, and I'm not quite sure how to deal with this problem. Is there anyone who can help me? Thanks

  You can use '' to insert some string: "yyyy-mm-dd'T'HH:MM:ss". But I suspect you'll also need a format specifier for the timezone offset.

  Have a look how the $ proc for datetime is implemented, then copy and paste the format string :)

  Wait, why are you doing it in such a hacky way with parsing the stringified date? This works just fine:

  import std/times
  
  let datetime = fromUnix(1623524119)
  
  echo datetime.format("HH:mm:ss")
  Run

  And yes MM is for months, mm is for minutes.

  https://github.com/treeform/chrono - my timestamp, calendar and timezone lib has no problems with this:

  import chrono
  
  let ts = Timestamp(1623524119)
  echo ts.formatIso()
  
  let time = parseIsoTs(ts.formatIso())
  echo time.format("{hour/2}:{minute/2}:{second/2}")
  Run

  Also the mm/MM bug would not happen.

  Thank you, that worked perfectly.
