When quoting a user the time parameter in the quote tag is changed when using iOS + safari.
Example, when a user quotes someone normal behavior would be:
[quote=Striker post_id=699836 time=1481464715 user_id=755]
Whereas quote behavior changes on iOS devices using safari.
[quote=Striker post_id=699836 time=<a href="tel:1481464715">1481464715</a> user_id=755]
