Cloudwatch custom event triggered instantly even after passing schedule time AWS

I am trying to use aws cloudwatch events for task scheduling in Node js, So , I created a cloudwatch event rule for this, Then I added a lambda function as a target. I am using event patterns to create a cloudwatch event rule here instead of scheduled expression. Now I am trying to add events to it at a scheduled time , but the event triggers instantly as soon as a put a event on cloudwatch. I don't know why this is happening, I researched a lot but didn't find anything relevant.

I used these official docs as reference :- https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CloudWatchEvents.html#putEvents-property https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/cloudwatch-examples-sending-events.html

I am new to AWS , please help me here.

This is the code performing the above mentioned action.

var params = {
        Name: 'DEMO_EVENT',
        RoleArn: 'iamroleArn',
        EventPattern: JSON.stringify({
            source: ['myapp.events'],
        }),
        State: 'ENABLED'
      };
      
      cwevents.putRule(params, function(err, rule) {
        if (err) {
          console.log("Error", err);
        } else {
          console.log("Success", rule.RuleArn);
          var params = {
            Rule: 'DEMO_EVENT',
            Targets: [
              {
                Arn: 'lambda function arn',
                Id: "default"
              }
            ]
          };
          
          cwevents.putTargets(params, function(err, data) {
            if (err) {
              console.log("Error", err);
            } else {
              console.log("Success", data);
              var params = {
                Entries: [
                  {
                    Detail: JSON.stringify({
                      "meetingNo": "82565852285"
                    }),
                    DetailType: 'meeting',
                    Resources: [
                        rule.RuleArn
                    ],
                    Source: 'myapp.events',
                    Time: new Date("2022-01-07T08:00:00Z"), // here I am sending the schedule time in utc
                  }
                ]
              };
              
              cwevents.putEvents(params, function(err, data) {
                if (err) {
                  console.log("Error", err);
                } else {
                  console.log("Success", data.Entries);
                }
              });
            }
          });
        }
      });
