Note: This tip is a follow-up to Martyn Durrant's Cool Solution Getting the Current Time into the UserApp Flow.
Here is an example on how to convert the date/time from YYYYMMDD12000000+ZONE to eDirectory format (e.g., 1167627600) in Policy Builder, for the date only:
<if-op-attr name="rbac-delegateStartDateString" op="available"/>
<token-convert-time dest-format="!CTIME" dest-tz="America/New_York"
