[Gnash-commit] /srv/bzr/gnash/trunk r10493: Add AMF encoding/decoding for Date objects, and test for it in SharedObjectTestRunner.

[Sandro Santilli]

------------------------------------------------------------

message:
  Add AMF encoding/decoding for Date objects, and test for it in 
SharedObjectTestRunner.
  NOTE: bitwise comparison fails due to different ending.
  Proprietary player now ends it with FF C4 00 while gnash keeps ending it with 
00.
  No idea how much this is related to Date itself (timezone info ?)
