Re: How to parse the timezone from a date/time string to a `TimeZone` type variable?

[mashingan]

something like this
    
    
    import times, strutils, sugar
    let
      dtStr = "2019/06/06 18:17:43 +02:00"
      dt = parse(dtStr, "YYYY/MM/dd HH:mm:ss zzz")
      myM10 = newTimezone("M-10",
        (x: Time) => ZonedTime(utcOffset: Hours.convert(Seconds, 10), time: x),
        (x: Time) => ZonedTime(utcOffset: Hours.convert(Seconds, 10), time: x))
      dtOffset = -1 * dtStr.rsplit(maxsplit=1)[1].split(":", 
maxsplit=1)[0].parseInt
      dtTz = newTimezone("DtTz",
        (x: Time) => ZonedTime(utcOffset: Hours.convert(Seconds, dtOffset), 
time: x),
        (x: Time) => ZonedTime(utcOffset: Hours.convert(Seconds, dtOffset), 
time: x))
      dtOrig = dt.inZone(dtTz)
      dtMy = dt.inZone(myM10)
    echo dt
    echo dt.timezone
    echo dt.utcOffset
    echo "========"
    echo dtOrig
    echo dtOrig.timezone
    echo dtOrig.utcOffset
    echo "========"
    echo dtMy
    echo dtMy.timezone
    echo dtMy.utcOffset
    
    
    Run

note:

  1. offset should really calculate hours and minutes offset
  2. idk why it should be reverted with -1 for setting the timezone (maybe 
because of time-relativity)
  3. you can write an array that populate with timezone at 1 hour interval at 
compile-time
  4. (or) you can provide some external timezone data and read it at 
compile-time or run-time



IMO, the current times module is more pleasant to work with compared to earlier 
version, kudos for the dev :3
