firebase javascript compare timesamp by seconds

I have a firebase database with some dates written down in what I think is the seconds format. I need to check if a day has passed since that date.

admin.firestore.Timestamp.now()._seconds;

is what I am using to get the current date. I now need to compare it, but I cannot find how to add a day to the date in the firebase, and am not sure if simply using < will compare them properly.

1633399860000 <-- (database date sample)

Thank you!

Solution

  • So...
    First of all the date format was milliseconds.
    It seems like it is not a problem to compare dates with a < or >.
    To add a day I tried to remove 86400000 (milliseconds) to today's date.

    The code is not giving problems for now so I'm guessing it is the right solution.
