I have some campaigns that have a set end date of 20120430. They've been set this way for a while and AdWords knows they're ending and according to their verbiage
"Your ads will stop showing after this date, unless you change it later."
When attempting to mutate the campaigns today I received the API Error "CANNOT_SET_DATE_TO_PAST" which is described as "Trying to modify a date into the past."
Since the day is not over and AdWords verbiage states the ads will stop showing *after* this date, shouldn't mutations still be allowed the day the campaign is set to expire?
