has anyone noticed any problems with events?

Code:
event	historic 	first_windmill
date	50

event	historic	earthquake_in_aleppo
date	58
position	257, 73

event	historic	science_alchemy_book
date	64
when checking out the event files i noticed that the 'date' is set to turns rather than an actual date... with the 'two turns per year' thing going on, i was wondering if anyone got the events earlier than they should be... and if that is so then the scripts might also have to be changed or we'll be getting early mongol invasions/eras...
