9126 :: Datetime parse format for round-trip "O"

• jmgomez (orginal) [2022-04-25T16:00:00+02:00] view original

  Hey guys,

  What would be the date format for the round trip O in nim? (https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-date-and-time-format-strings#Roundtrip)

  So I can do

  
  
  
  let date = parse ("2022-04-25T13:03:28.8936219Z", ???, utc())
  
  Run

  Thanks!

  Juan

  It seems this pattern is not yet supported. (While googling the "fffffffK" pattern i found this informative gist: https://gist.github.com/y-gagar1n/8469484 maybe someone will pr times.nim someday.)

  Seconds fractions are not commonly supported or found in the wild, but you can still parse them with my calendar/timestamp/timezone library:

  github: https://github.com/treeform/chrono docs: https://nimdocs.com/treeform/chrono/chrono.html#format-specification

  
  import chrono
  
  let cal = parseCalendar(
    "{year/4}-{month/2}-{day/2}T{hour/2}:{minute/2}:{second/2}.{secondFraction}Z",
    "2022-04-25T13:03:28.8936219Z"
  )
  
  echo cal
  echo cal.second
  echo cal.secondFraction
  Run

  Just nimble install chrono to get it.
