# MessageMinDate

The `MessageMinDate` parameter filters messages (and other types of item such as calendar items and tasks) by their modified date. The connector only retrieves items that were modified after the specified date.

Specify the date in UTC time using one of the following formats:

- A date in the format `yyyy/MM/dd hh:mm:ss`, for example `2014/05/29 00:00:00`.
- A date in epoch seconds, for example `1401364800`.

- A relative date, starting with the character ‘`-`’ followed by a time duration. The time duration is relative to the time when the task begins, which results in a rolling limit. Relative dates support the units year(s), month(s), week(s), day(s), hour(s), minute(s), and second(s). You can shorten the value by abbreviating the units to their first letter (months abbreviates to m, minutes to n). For example:

         -3months 1week
         -3m 1w

  A single value without a unit is read in seconds, so the following are equivalent:

         -1day
         -86400s
         -86400

  Positive values are accepted if they begin with the character '`+`', but be aware that positive values represent times in the future.

With relative dates, items that were previously ingested but no longer meet the limit are removed from the IDOL index.
