The תוסף לקביעת תאריך ושעת פוסטים בישרא-בלוג is a Chrome add-on developed by PhistucK. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This free add-on allows users to set the date and time for posts on the ישרא-בלוג platform as part of the regular editor.

With this add-on, users can change the date and time of both new and old posts. However, it is important to note that ישרא-בלוג limits the number of date and time changes, so users should ensure that the desired date and time are correct to avoid any mistakes.

To use the add-on, users need to modify the editing mode and below the post writing box, a field for setting the date and time will be added.
