Subject: [OASIS Issue Tracker] (ODATA-1123) Allow 24:00:00 for Edm.TimeOfDay (public review comment c201710e00003)
[ https://issues.oasis-open.org/browse/ODATA-1123?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ralf Handl updated ODATA-1123: ------------------------------ Fix Version/s: (was: V4.01_CS01) > Allow 24:00:00 for Edm.TimeOfDay (public review comment c201710e00003) > ---------------------------------------------------------------------- > > Key: ODATA-1123 > URL: https://issues.oasis-open.org/browse/ODATA-1123 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: New Feature > Components: CSDL JSON , CSDL XML > Affects Versions: V4.01_CSD03, V4.01_CSD02 > Environment: [Proposed] > Reporter: Ralf Handl > > Public review comment https://lists.oasis-open.org/archives/odata-comment/201710/msg00003.html > CSDL 4.01 permits Edm.TimeOfDay values to range from 00:00:00 to 23:59:59.999*. > However existing systems (e.g. SAP backends) frequently utilize 24:00:00 to indicate end-of-day. Requiring these values to be transmitted (e.g. to clients) as 23:59:59.999* could result in round-trip data loss. > In fact such SAP systems (for V2/V4) already will return PT24H or normalization-equivalent (for the V2 format of Edm.Time using XSD duration) or 24:00:00 (for the V4 format of Edm.TimeOfDay using XSD time), which is non-compliant with OData V2-V4 specifications. > To improve interoperability, it would be preferable to standardize this behaviour. > Note that the lexical format for XSD time permits 24:00:00, as it is the left-truncation of dateTime lexical representation, and dateTime lexical representation (see https://www.w3.org/TR/xmlschema-2/#dateTime) states: > - hh is a two-digit numeral that represents the hour; '24' is permitted if the minutes and seconds represented are zero, and the dateTime value so represented is the first instant of the following day (the hour property of a dateTime object in the ·value space· cannot have a value greater than 23); -- This message was sent by Atlassian JIRA (v6.2.2#6258)
