AirWatch Console 9.1.3
Bootstrap Packages effective date is not set correctly if the Administrator's time zone is not the same as the server time.
A current workaround is to change the Admin time zone to match the server time zone when uploading a bootstrap package.
The time zone can be changed by editing the administrator settings under Accounts > Administrators > List View. Select the admin user to change the time zone and save. Alternatively, if you’re logged in as the admin, you can also use the “Manage Account Settings” in the top right corner of the AirWatch Console under the administrator name.
This has been resolved in AirWatch 9.1.4 and 9.2.
