Converting pymongo Milliseconds to Formatted Dates in Python

Handling date and time data correctly is crucial when working with databases and APIs that often represent timestamps in milliseconds since the epoch. In this guide, we will explore a common issue that arises when converting such timestamps using Python’s datetime module, specifically how to convert a pymongo representation of time from milliseconds to a standard formatted date string.

The Problem

Imagine you have a timestamp represented in milliseconds, like 1614100501543, which you fetch from a pymongo collection. The structure might look something like this:

However, when you run this code, you encounter an error:

The Solution

To correctly convert milliseconds to a formatted date in Python, you just need to follow a simple step: divide the milliseconds by 1000 to convert them into seconds. Here's how you can do it:

Step-by-Step Solution

Extract the Milliseconds: Grab your timestamp in milliseconds.

Convert to Seconds: Divide the milliseconds by 1000.

Use utcfromtimestamp(): Call the method with the adjusted seconds value.

Format the Date: Use strftime() to format the date as desired.

Implementation

Here is the revised code that will solve the issue:
