To publish/unpublish an existing asset, edit the asset, and click the Publish / Unpublish link. Select the environment(s) and language(s) you wish to publish/unpublish the asset to/from.
The Publish At / Unpublish At option that appears on the Publish Asset and the Unpublish Asset dialog boxes allow you to publish or unpublish an asset either immediately or schedule it by means of the Now and Publish Later / Unpublish Later sub-options, respectively.
The Now option publishes/unpublishes an asset immediately, and the Publish Later / Unpublish Later option allows you to publish/unpublish an asset at a later date/time. When you select this sub-option, you will be asked to select the date and time of publishing. On clicking this textbox, you will be prompted to enter the exact date, time (hour-min), and the timezone.
On selecting a timezone that follows daylight saving time (DST), Contentstack will display a help text at the bottom of the textbox that highlights the effective publishing date, time, and timezone along with DST adjustments. The effective publishing date specifies the publishing date in local time for the user publishing the entry.
Note: The DST time difference is one hour.
