ZM_WEB_EVENT_SORT_ORDER
Events in lists can be initially ordered in any way you want. This option controls what order (ascending or descending) is used to sort them. You can modify this ordering from filters or by clicking on headings in the lists themselves. Bear in mind however that the 'Prev' and 'Next' links, when scrolling through events, relate to the ordering in the lists and so not always to time based ordering.
