AWS documentdb documentation change

Service: documentdb · 2026-03-31 · Documentation low

File: documentdb/latest/developerguide/currentDate.md

Summary

Added new documentation page for the $currentDate operator in Amazon DocumentDB, including parameters, MongoDB shell examples, and code examples in Node.js and Python with secure connection strings

Security assessment

This change adds new documentation for a standard date operator. The code examples include secure connection parameters (TLS=true, tlsCAFile=global-bundle.pem) which demonstrate security best practices for connecting to DocumentDB, but there is no evidence this addresses a specific security vulnerability or incident.

+# $currentDate
+
+The `$currentDate` operator is used to set the value of a field to the current date and time. This operator is useful for automatically updating a field with the current timestamp when a document is inserted or updated.
+
+**Parameters**
+
+  * `field`: The field to update with the current date and time.
+
+  * `type`: (optional) Specifies the BSON type to use for the current date. Can be either `date` or `timestamp`.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$currentDate` operator to set the `lastModified` field to the current date and time when a new document is inserted.
+
+**Create sample documents**
+    
+    
+    db.users.insert({
+      name: "John Doe",
+      email: "[email protected]"
+    })
+
+**Query example**
+    
+    
+    db.users.updateOne(
+      { name: "John Doe" },
+      { $currentDate: { lastModified: true } }
+    )
+
+**View updated document**
+    
+    
+    db.users.findOne({ name: "John Doe" })
+
+**Output**
+    
+    
+    {
+      _id: ObjectId('...'),
+      name: 'John Doe',
+      email: '[email protected]',
+      lastModified: ISODate('2025-10-25T22:50:29.963Z')
+    }
