How to Set Up Weekly Rollup Timestamps in a Bash Script

If you're running a bash script that requires API calls with specific timestamps, you may often need to calculate these timestamps based on the current week. A common scenario is to set rolling timestamps for every Monday at 7 AM PST and every Sunday at 11:59 PM PST. This blog will guide you through the necessary changes you'll need to make to your bash script to achieve this.

The Problem: Setting Weekly Rollup Timestamps

In your initial script, you were using the following methods to calculate the start and end timestamps:

While this approach can get you part of the way there, it wouldn't yield your desired output of starting from Monday 7 AM PST and ending on Sunday 11:59 PM PST of the current week. Let’s take a deeper look at the changes needed to meet this requirement.

The Solution: Updating Your Bash Script

To modify your script accordingly, you'll need to adapt the way you calculate both start and end timestamps. Below are the specific adjustments you need to make:

Step 1: Set the Start Timestamp

Change your start timestamp calculation to ensure it adjusts for your specific time zone (PST) and sets it to 7 AM on Monday:

Explanation: This command sets the timezone for the date command to PST (“America/Los_Angeles”) and calculates the timestamp for the upcoming Monday at 7 AM.

Step 2: Set the End Timestamp

Next, revise your end timestamp calculation to capture the final moment of the week (Sunday) at 11:59 PM PST:

Explanation: Similar to the start timestamp, this command calculates the timestamp for one minute before the next Monday, which falls at 11:59 PM on Sunday.

Conclusion

In summary, by updating your bash script to correctly set a start timestamp for Monday at 7 AM PST and an end timestamp for Sunday at 11:59 PM PST, you improve the accuracy of your API calls significantly. This process not only helps with weekly reporting but also ensures you are working with the correct data timeframe.
