Firebase Date Storage Goes Wrong

So I am trying to store a date in Firebase like this: var fb = new Firebase(FIREBASE_URL); var syncData = $firebase(fb); var date = new Date(2014, 0, 1); c

Solution 1:

Store dates using getTime(). When your read them back and want to display to users, use new Date(/* getTime value here */), and they will display correctly in any time zone. Additionally, client clocks may be skewed, so you should use Firebase.ServerValue.TIMESTAMP instead of new Date().

Solution 2:

I figured out why Firebase does this, my system is on GMT+2 time and the new date(year, month, day) constructor constructs the date at midnight. Firebase however saves the date as a UTC date so 2 hours get subtracted from the date, which leads to every date being saved at 10PM the day before the intended date.

This is also why new Date() did work, because a date at the current hour with 2 hours subtracted still works.

A workaround for this is just setting every date at 12:00 PM instead of 12:00 AM. If anyone knows of any better workarounds, it would be appreciated.

Solution 3:

This answer might only be relevant for languages where you have a method for this, but in C# I can do dateFromFireBase.ToLocalTime(). This assumes that the date is saved in the same time zone as you load it in, which is the case for me. This should be possible in javascript too.

Solution 4:

Also date store like this

var cdate =  newDate(); //2016-06-14 11:34:53var current_date = cdate.getFullYear()+"-"+cdate.getDate()+"-"+cdate.getMonth()+" "+cdate.getHours() + ":" + cdate.getMinutes() + ":" + cdate.getSeconds();
