Tasks are impossible to postpone (they keep returning to the original due date) or postpone to the wrong day or time.
Your timezone setting in Remember The Milk does not match the system timezone on a computer where you use the site. Timezone mismatches may prevent tasks from being postponed correctly.
Check to make sure that your timezone on the Settings screen in Remember The Milk matches your system timezone on any computers where you use the site. It's particularly important to check the location of the timezone to make sure that they match as well (to ensure that daylight savings time is observed correctly for your account).
Note about timezones: If you're viewing Remember The Milk from a different timezone -- for example, when traveling -- your tasks may appear on the wrong day or postpone incorrectly. Unfortunately Remember The Milk doesn't currently support shifting timezones; when a due date is set in one timezone, the task will be due at the start of that day (that is, midnight) in that timezone. Thus, any timezone offsets can affect the display of your tasks.
Aside from correcting any discrepancy between your Remember The Milk and system's timezones, if you encounter this problem you should be able to correct it for a given task by resetting a task's due date (that is, simply editing the due date and pressing Enter should suffice). If you've moved permanently, please contact us so we can correct this for all of your tasks.
