  1. OMG Issue

UPDM2 — and define ISO8601DateTime

  • Key: UPDM2-8
  • Legacy Issue Number: 16640
  • Status: closed  
  • Source: Change Vision ( Michael Chonoles)
  • Summary:

    The text for the definition in is not internally consistent, nor consistent with ISO8601

    Current Text

    “MODAF: A date and time specified in the ISO8601 date-time format including timezone designator (TZD):
    YYYY-MMDDThh:mm:ssTZD So, 7:20pm and 30 seconds on 30th July 2005 in the CET timezone would be represented as “2005- 07-30T19:20:30+01 :00.”

    You may notice that the “-“ and “ “ in the pattern definition and in the example are not consistent. The ISO definition is as follows:


    Where TZD= Z for Zulu (GMT)

    = or ±NN:NN

    With the example of 7:20 pm and 30 seconds on 30th July 2005 in the CET (Central European)Timezone would be


    Suggested Fix.

    a) Correct Pattern definition

    YYYY-MMDDThh:mm:ssTZD à YYYY-MM-DDThh:mm:ssTZD (where TZD=Z or ±NN:NN)

    This adds the – between the MM and DD subfields, and explains the possible values for the TZD field

    b) Correct Example

    2005- 07-30T19:20:30+01 :00 à 2005-07-30T19:20:30+01:00

    This drops the extra space before the month and after the timezone offset hour.
