In the latest version of TimelineJS we changed how dates are read so that you have more control over how that date is interpreted. TimelineJS now has precision dating.
For example:
If you enter 2000 in the date column, it will read as 2000.
01/2000 will read as January, 2000 and
01/01/2000 will read as January 1st, 2000.
This might affect some of your existing timelines. The fix is pretty easy though, just fix your dates.
If you're using Google Spreadsheets as your source, you may run into an issue when you try and fix your dates. The date column in the older versions of the template were set to format the dates as mm/dd/yyyy tt:tt. So you type in 2000 and the spreadsheet reformats it to read 01/01/2000 00:00.
To fix this, just select the date columns and click "Format > Number > Plain Text". (see the screenshot below).
