Chart Validity

Hi all,

Quick Question Regarding Time Validity of Significant Prognostic & Wind Charts,

When a Chart is Valid say 18:00 , does this mean up until 18:00, between 12:00 and 18:00

or

Valid AT 18:00 ?

for example a 1hr flight departing 14:00, should they have 12:00 , 18:00 or both?

thanks,
-Jd
