Does anyone know how to create the REV, r开发者_运维问答evision, for the VCard? I looked on Wikipedia and it says combination of date and time, but doesn't really say what the exact method is. Thanks.
Here is an extract from RFC2426 (Section 3.6.4):
Type name: REV
Type purpose: To specify revision information about the current vCard.
Type encoding: 8-bit
Type value: The default is a single date-time value. Can also be reset to a single date value.
Type special notes: The value distinguishes the current revision of the information in this vCard for other renditions of the information.
Type example:
REV:1995-10-31T22:27:10Z
REV:1997-11-15
