Storing Date and Time in Meteor for efficient range queries

I'm working on an app that requires creating objects with a startDate displayed in 3 different timezones within the browser, including the exact time. I need to store the date in a way that allows for queries like "give me all dates between X and Y" while also being able to parse it into those 3 timezones.

My main question is what's the best way to save and retrieve the date and time later for querying? Should I consider using moment.js? One idea I had was storing both the date and time as a single Unix timestamp in the database, then parsing it into the specific date and time with the relevant timezone when reading. Is this a good approach, or should I stick to saving it as a plain JavaScript Date object? Can MongoDB query Unix timestamps as date ranges, or does it require plain Date objects?

Any insights would be much appreciated!

If you want to learn all about this topic, check out the resource available here. Here are some key points to remember:

  • Make sure to store dates as JavaScript Date objects for better query performance without the need for conversions.

  • When performing range queries, use syntax like: 

    Posts.find({creation_date: {$gte: startDate, $lt: endDate}})

  • To prevent clock skew issues, consider having the server handle inserts or utilize the timesync package.

  • For formatting dates in different timezones, try using moment-timezone. For example: 

    moment(date).tz("America/New_York").format('l LT')
