How to do pm2 log formatting?

Question

Hi I have implemented pm2.Now I am getting timestamp in each line.

//Current log

2021-05-04T00:34:49:       { MongoError: server instance pool was destroyed
2021-05-04T00:34:49:           at Function.MongoError.create (C:\Article\snode_modules\mongodb-core\lib\error.js:29:11)
2021-05-04T00:34:49:           at basicWriteValidations (C:\Articles\node_modules\mongodb-core\lib\topologies\server.js:448:51)

2021-05-04T00:34:49:           at process._tickCallback (internal/process/next_tick.js:61:11)

I want to achieve this log format means one time timestamp for each error and log level in pm2

2021-05-04T00:34:49: [Error]       { MongoError: server instance pool was destroyed
          at Function.MongoError.create (C:\Article\snode_modules\mongodb-core\lib\error.js:29:11)

          at process._tickCallback (internal/process/next_tick.js:61:11)

Here is my config file:-

module.exports = {
  apps : [{
    name   : "app",
    script : "./app.js",
    error_file : "/err.log",
    out_file : "/out.log",
    time: true

  }]
}

Thanks in advance!!
