Some dates not showing on timeline only in Firefox

[tarsierspectral]

I don't know why but I have dates that don't show up in Firefox on Mac and PC. What gives?

[erochest]

We're going to need more information than that. What are the dates? Are there any errors that show up in the Firefox Web Console? Do you have any links?

[tarsierspectral]

The dates are:
-001600 to -00850
-000300 to -000350
000350 to 000550
000500 to 001500
001500 to 001900

The Firefox console shows the following 3 errors:
window.controllers is deprecated. do not use it for ua detection
mutating the [[Prototype]] of an object will cause your code to run very slowly
deprecation warning moment construction falls back to js date. this is discouraged and will be removed in upcoming major release. Refer to moment/moment#1407 for more info

For testing purposes I created a new Neatline exhibit and added things to the timeline. The same thing is happening. Not all records show, only 3 records. Seems like no matter what I put on the timeline only 3 records show.

Does this format make any difference?

-000500-01-01

Date parsers in the various browsers appear to be diverging a bit, particularity when they fall back to the JavaScript parser form the moment library.

Hi @waynegraham.
I tried:
-0001600-01-01 for start date
-000850-01-01 for end date

It made no difference.

[tarsierspectral]

OK, I figured it out. It was a matter of adding and removing zeros from some dates. Doing this would make multiple dates to show up

[waynegraham]

BC dates are perplexing in JavaScript...what were the final values you had to use?

[tarsierspectral]

For -001600 to -00850 I used -001600 to -000850
For -000300 to -000350 I used -000300 to -000350
For 000350 to 000550 I used 0350 to 0550
For 000500 to 001500 I used 0500 to 1500
For 001500 to 001900 I used 1500 to 1900

Could the directions on the help menu use clarification?
