### Summary Expires_at date shown on project_members page shows one day before actual expiration date. ### Steps to reproduce Either use _Add member_ or _Share with group_ to add a member or group, along with an expiration date some time in the future. After you submit the form, you should immediately see that the date displayed is one day before the previously set date. ### Relevant logs and/or screenshots   #### Results of GitLab environment info This happens on [gitlab.com](https://gitlab.com/cwest1/test-share-expiration) as well. I added @dstanley to the project with an expiration of 2018-10-31 and now it shows 2018-10-30. ### Possible fixes I believe it's an issue with the calendar picker. If I temporarily remove the 'js-access-expiration-date' from the view in `/app/views/shared/members/_group.html.haml`, thus disabling the date picker, then it displays the correct date.
