Issues with Date\Time picker on service portal - getting message javascript error "zone.offset has been deprecated in favor of zone.utcOffset"? - Support and Troubleshooting

Issues with Date\Time picker on service portal - getting message javascript error "zone.offset has been deprecated in favor of zone.utcOffset"? Description  Symptoms While using date picker with the date / date time fields on service portal, getting below javascript error,

moment-timezone-with-data.js:476 zone.offset has been deprecated in favor of zone.utcOffset Complete error stack is shown in below screenshot,

Release Any supported release.

Cause Older version of moment.js third party library (/ajax/libs/moment.js/2.22.2/moment.min.js) was included in the out of the box provided "moment.js" widget dependency (https://InstanceName.service-now.com/nav_to.do?uri=sp_dependency.do?sys_id=db6689c1cb11120000f8d856634c9c3b).

Hence system loads the older version of moment.js in DOM and eventually we get the error "zone.offset has been deprecated in favor of zone.utcOffset" while accessing date /date time field since older version of moment.js library has deprecated methods.

Resolution Out of the box provided moment.js widget dependency has following definition,

Name = moment Application = Global Included on Page load = false

JS Includes, order = 200, JS Include = /scripts/thirdparty/moment-timezone-0.4.0/moment-timezone-utils.js, JS file URL = /scripts/thirdparty/moment-timezone-0.4.0/moment-timezone-utils.js

order = 200, JS Include = /scripts/thirdparty/moment-jdateformatparser-1.0.2/moment-jdateformatparser.js, JS file URL = /scripts/thirdparty/moment-jdateformatparser-1.0.2/moment-jdateformatparser.js Hence, we recommend, updating your "moment.js" widget dependency as per the out of the box definition

OR

Keep the out of the box provided version and delete the custom moment.js widget dependency.
