[OASIS Issue Tracker] Commented: (ODATA-112) DateTime[Offset]: allow 24:00[:00] in time part

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

    [ http://tools.oasis-open.org/issues/browse/ODATA-112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31253#action_31253 ] 

Michael Pizzo commented on ODATA-112:
-------------------------------------

OData is an HTTP protocol.

HTTP references RFC1123 which in turn references RFC822 for time format. 

The ABNF in Section 5.1, Syntax, of RFC822 specifies the following:

hour        =  2DIGIT ":" 2DIGIT [":" 2DIGIT]
                                                 ; 00:00:00 - 23:59:59

Many languages, frameworks, and storage systems don't support 24:00; neither does SQL. Introducing it would be disruptive to those systems.
