Describes the earliest (oldest) date to use in a date range filter based on item modification time. Must be specified if ModTimeTo is specified. Either the StartTimeFrom, EndTimeFrom, or ModTimeFrom filter must be specified. If you do not specify the correspoding To filter, it is set to the time you make the call.
For better results, the time period you use should be less than 48 hours.
If an unexpected item is returned (including an old item or an unchanged active item), please ignore the item. Although a maintenance process may have triggered a change in the modification time, item characteristics are unchanged.
See the
Field Index to learn which calls use ModTimeFrom.
