Issue with PCIM-04

• Semantics and syntax for the time-range
  properties in PolicyTimePeriodCondition class
  should match those specified in RFC 2445
  (iCalendar)
• Subsequent discussion revealed that there may
  also be an issue with the representation of time
  zones in the ApplicableTimeZone property

7
Proposed Resolution

• Accept the proposed changes to the time-range
  properties, but leave the time zone
  representation as it is
• TimePeriod property period-explicit syntax from
  section 4.3.9 of RFC 2445 still need to decide
  on representation of open ranges
• TimeOfDayMask property
• Thhmmss/Thhmmss
