Narrative:

Cleared to cross vibes intersection at 13000 ft. During descent, #1 flight attendant distracted crew with passenger request and I failed to reset local altimeter passing FL180. Autoplt captured 13000 ft and leveled off. Informed by ZNY that altitude reporting indicated 600 ft low. WX was VFR and I believe there was no conflict.
