  21  * \brief Assert that pcmk__time_format_hr() produced expected result
  22  *
  23  * \param[in] format     Time format string
  24  * \param[in] expected   Assertion succeeds if result matches this
  25  * \param[in] alternate  If this is not NULL, assertion may also succeed if
  26  *                       result matches this
  27  *
  28  * \note This allows two possible results because different strftime()
  29  *       implementations handle certain format syntax differently.
