You need to add some comments to explain your algorithm, why adding 14 hours.

Hi, yes earlier I was manually setting the timezoneOffset to -14 hours, which is incorrect, while working on this project, I learned a function getTimezoneOffset() and it serves our need.

var lastWeekMonth = extendedLastWeek.getMonth() + 1;
var lastWeekDay = extendedLastWeek.getDate();
var lastWeekYear = extendedLastWeek.getFullYear();
var lastWeekDisplayPadded =
('0000' + lastWeekYear.toString()).slice(-4) +

issue (complexity): Consider extracting the date transformation logic into a shared helper function to avoid repetition and improve code maintainability

Extract a shared helper to handle the date transformation so you don’t repeat the setHours and offset logic. For example:

function formatDateWithOffset(date, isStart) {
  if (isStart) {
    date.setHours(0, 0, 0, 0);
  } else {
    date.setHours(23, 59, 59, 999);
  }
  const offsetHours = 14;
  const utc = new Date(date.getTime() + (offsetHours * 60 * 60 * 1000));
  return utc.toISOString().slice(0, 19) + "Z";
}

Then update your functions as follows:

function getLastWeek() {
  const today = new Date();
  const daysBack = gsoc === 0 ? 7 : 1;
  const lastWeek = new Date(today.getFullYear(), today.getMonth(), today.getDate() - daysBack);
  return formatDateWithOffset(lastWeek, true);
}

function getToday() {
  const today = new Date();
  return formatDateWithOffset(today, false);
}

This refactoring reduces duplication while keeping the functionality identical.

it is used in only two functions, also its a single line, I don't think a function is necessary.

I'll respond to the comment by the developer:

While I understand your perspective that the code is used in only two functions and appears to be a single line, creating a helper function offers several benefits:

  1. Code Readability: The extracted function makes the date transformation logic more explicit and easier to understand at a glance.

  2. Maintainability: If the date transformation logic needs to change in the future, you'll only need to modify it in one place.

  3. Reusability: Even if it's currently used in just two functions, having a dedicated helper makes it easier to reuse the logic elsewhere if needed.

  4. Consistency: The helper ensures that date transformations are handled consistently across different parts of the code.

The proposed refactoring is lightweight and doesn't add unnecessary complexity. It actually simplifies the existing code by:

  • Removing manual string formatting
  • Centralizing the time zone and offset logic
  • Making the intent of the code clearer

I recommend considering the proposed refactoring, but if you feel strongly against it, that's okay too. The most important thing is maintaining clean, understandable code.

Would you like to discuss this further or share your thoughts on the suggested approach?
