extract time-values from variable text

[WilliamV]

Hereby the cell:

"From 07/09/11 till 13/06/12 Ma Gesloten Di Gesloten Wo Open from 14:00 till 16:55 Do Gesloten Vr Gesloten Za Gesloten Zo Gesloten Meer uitleg : Geen lessen tijdens de schoolvakanties "

I need to create a macro/script to extract 14:00 and 16:55 in above text, these are two timevalues (from and till). They need to be extracted each to a new cell in the same format HH:MM. Text is variable.
I have a variable column with values, so the macro/script needs to applie to a whole colum (range x:x)
Please advise!
Thx!
