Summary

Entire documentation page for the $dateToString aggregation operator was removed, including all content, examples, and code samples

Security assessment

This change removes documentation for a date formatting function in Amazon DocumentDB. There is no evidence in the diff that this removal is related to a security vulnerability or incident. The removed content appears to be standard documentation for a MongoDB aggregation operator with no security-specific content. This appears to be routine documentation maintenance, restructuring, or deprecation rather than a security-related change.

-# $dateToString
-
-The `$dateToString` aggregation operator in Amazon DocumentDB is used to convert a date or timestamp value to a string representation. This is useful when you need to format the date and time in a specific way for display or further processing.
-
-**Parameters**
-
-  * `date`: The date or timestamp value to be converted to a string.
-
-  * `format`: A string that specifies the format in which the date should be represented. The format string can include various format specifiers, such as `%Y` for the four-digit year, `%m` for the two-digit month, `%d` for the two-digit day of the month, etc.
-
-  * `timezone`: (optional) The time zone to use for the conversion. If not specified, the time zone of the server hosting the Amazon DocumentDB cluster is used.
-
-  * `onNull`: (optional) The value to be returned if the `date` parameter is `null`.

-## Example (MongoDB Shell)
-
-The following example demonstrates the usage of the `$dateToString` operator to format the `logDate` field of the `missionLog` collection.
-
-**Create sample documents**
-    
-    
-    db.missionLog.insertMany([
-      { _id: 1, "event":"missionStart", logDate: new Date("2020-03-15T13:41:33Z") },
-      { _id: 2, "event":"jumpPoint1", logDate: new Date("2020-03-15T13:45:34Z") },
-      { _id: 3, "event":"jumpPoint2", logDate: new Date("2020-03-15T13:48:21Z") },
-      { _id: 4, "event":"jumpPoint3", logDate: new Date("2020-03-15T13:52:09Z") },
-      { _id: 5, "event":"missionEnd", logDate: new Date("2020-03-15T13:58:44Z") }
-    ]);
-
-**Query example**
-    
-    
-    db.missionLog.aggregate([
-      {
-        $project: {
-          event: "$event",
-          logDateFormatted: {
-            $dateToString: {
-              format: "%Y-%m-%d %H:%M:%S",
-              date: "$logDate"
-            }
-          }
-        }
-      }
-    ])
-
-**Output**
-    
-    
-    [
-      {
-        "_id": 1,
-        "event": "missionStart",
-        "logDateFormatted": "2020-03-15 13:41:33"
-      },
-      {
-        "_id": 2,
-        "event": "jumpPoint1",
-        "logDateFormatted": "2020-03-15 13:45:34"
-      },
-      {
-        "_id": 3,
-        "event": "jumpPoint2",
-        "logDateFormatted": "2020-03-15 13:48:21"
-      },
-      {
-        "_id": 4,
-        "event": "jumpPoint3",
-        "logDateFormatted": "2020-03-15 13:52:09"
-      },
-      {
-        "_id": 5,
-        "event": "missionEnd",
-        "logDateFormatted": "2020-03-15 13:58:44"
-      }
