I posted an update to PECL package of Syck.

Changelog:

• fixed handling of invalid merge-references [reported by Sascha Kettler]

• fixed tsrm-incompatibility introduced in 0.9

• added support for timestamps in syck_load (thanks to Derick for a hint)

• added support for DateTime in syck_dump

• fixed dumping of associative-arrays

Update is highly recommended for everyone
