BullMQ, an advanced queue-based job and message system for Node.js, does not inherently understand or manage timezones. It schedules jobs based on the server's local time by default. However, you can manage timezones manually, typically by converting all dates/times to UTC before scheduling jobs.
Date object uses the local server's timezone when creating new instances but can be easily converted to UTC.
Here an example:
In this code, we get the current time in UTC and schedule a job to be processed an hour later (also in UTC). The delay is calculated as the difference between the UTC times of
If you're dealing with user-specific timezones, convert the user's local time to UTC when scheduling jobs. Libraries like Moment.js or Luxon might help with these conversions.
Remember, when working with timezones, it's usually best to convert and store times in UTC, then convert to the user's local timezone when displaying times to the user.
