Gershon Janssen: T: elaborates on the WD02 document contents
Gershon Janssen: T: feedback on all aspects of the document are most welcome
Gershon Janssen: Proposal format for time granularity to break it into 100s of seconds or miliseconds
Gershon Janssen: WC: Should there be a restriction on the granularity of an iCalendar event?
Gershon Janssen: Is there a formal mechanism to restrict the time to seconds?

<year>2008</year><month>2</month><day>5</day>
<hour>19</hour><minute>12</minute><second>24</second>
Gershon Janssen: Carl Mattocks: word or label for the element granularity; can we talk about precision in our
discussions?
Gershon Janssen: WC: granularity and precision are different things, which is meant?
Gershon Janssen: Carl Mattocks: unclear what we are talking about when using these words
Gershon Janssen: T: New words for being more accurate in describing things are most welcome.
Gershon Janssen: WC: we should work towards a consistant terminology across all standards, using the same concepts.
Gershon Janssen: T: Q for Dave: is there a definition on granularity in the iCalendar spec?
Carl Mattocks: Section 3.2 uses Granularity as name for element and explains it is used to define precision and
communicate precisely .. should the element be named Precision Granularity
Toby Considine: Carl: Precision is focus of conversation...
Gershon Janssen: Dave: Not below seconds as iCalendar is intended for human interactions, but will look into it for a
final answer on this.
Gershon Janssen: Dave: likes the concepts on precesion and resolution
Gershon Janssen: WC: research on specs to get to a consistent description on the concepts.
