Tempus-dominus: Deprecation warning: moment construction falls back to js Date

[am11]

This deprecated warning is pretty annoying as it consumes about 30 lines in console.

Deprecation warning: moment construction falls back to js Date. This is discouraged and will be removed in upcoming major release. Please refer to https://github.com/moment/moment/issues/1407 for more info.

I have explicitly disabled console.warn to avoid this warning using the cache-and-restore technique:

var cachedWarn = console.warn;
console.warn = function () { };
$mySelector.datetimepicker({...})
console.warn = cachedWarn;

I also get this warning. Does anyone know if it's definitely the datepicker that is causing it?

[mrndig]

Yes, it's the datepicker what is causing the warnings. It is because moment.js changed its constructor, and this datepicker uses moment.js. More info on the issue:

As @mrndig metioned, just overwrite createFromInputFallback, warning disappeared.

For what it's worth, I was able to remove the warning in my code by doing:

datePickerElement.datetimepicker().datetimepicker('defaultDate', initialDate);

instead of:

datePickerElement.datetimepicker({ defaultDate: initialDate });

[bouskdav]

This is caused by unreliable date/time formats. Just use any ISO one. e.g.:
instead of
defaultDate: "11/1/2013"
use
defaultDate: "2013-01-11"

probably @Eonasdan could change the documentation accordingly - just change the format?

[AndiZ23]

Agree with @bouskdav
So whenever using a date string to config the datetimepicker, just use a JavaScript Date() object and call the toISOString() method.
For example, my case was setting today as the maxDate:
(javascript) datetimepickerElement.datetimepicker({ maxDate: new Date().toISOString(), format: "MM/DD/YYYY" });
