Well if you are in CAP 371 land the answer is "no, you were not acclimatised. If you had "shifted" by more than 2 hours from the time zone of departure you need 3 local nights on the new time zone, free of duty, before you are Acclimatised again...being at home or away has nothing to do with it.
Instead of bending the acclimatised defn. could the Company have used "Commanders discretion" to make it legal for you to operate?
.....and not told you?
