  • yyyy is the year
  • mm is the month (with leading zero)
  • dd is the day (with leading zero)
  • nn is an incrementing number (starting from 00) that is used in case two separate upgrades have been added during the same day
Returns
int E.g. 2016123101

 needsIncrementOffset ()
 Should the run() method receive an offset representing all processed items?If true, run() will receive as $offset the number of items already processed. This is useful if you are only modifying data, and need to use the $offset in a function like elgg_get_entities*() to know how many to skip over.If false, run() will receive as $offset the total number of failures. This should be used if your process deletes or moves data out of the way of the process. E.g. if you delete 50 objects on each run(), you may still use the $offset to skip objects that already failed once.
