At this time Remember The Milk doesn't support shifting timezones; when a due date is set in one timezone, the task will be due at the start of that day (i.e. midnight) in that timezone. Thus, when postponing from a different timezone, the incorrect date will be displayed; sorry for the inconvenience.
You should be able to correct this by resetting a task's due date. In the web app, simply editing the due date and pressing Enter should suffice. (After returning home, you may want to do this for all tasks you added or modified while traveling; the addedAfter: search operator may help. More info on searching can be found here.)
Hope this helps!
