  * Auto EOT time, else NPR (next payment time).

  * @package s2Member\Utilities
  * @since 150713
  *
  * @param int|string $user_id Optional. Defaults to the current User's ID.
  * @param bool $check_gateway Defaults to a true value. If this is false, it is only possible to return a fixed EOT time.
  * 	In other words, if this is false and there is no EOT time, empty values will be returned. Be careful with this, because not checking
  * 	the payment gateway can result in an inaccurate return value. Only set to false if you want to limit the check to a fixed hard-coded EOT time.
  * @param string $favor Defaults to a value of `fixed`; i.e., if a fixed EOT time is available, that is returned in favor of a next payment time.
  * 	You can set this to `next` if you'd like to favor a next payment time (when applicable) instead of returning a fixed EOT time.
  *
  * @return array An associative array of EOT details; with the following elements.
  *
  * - `type` One of `fixed` (a fixed EOT time), `next` (next payment time; i.e., an ongoing recurring subscription); or an empty string if there is no EOT for the user.
  * - `time` The timestamp (UTC time) that represents the EOT (End Of Term); else `0` if there is no EOT time.
  * - `tense` If time is now (or earlier) this will be `past`. If time is in the future, this will be `future`. If there is no time, this is an empty string.
  * - `debug` A string of details that explain to a developer what was returned. For debugging only.
