如何获取时间戳以在Tumblr中显示，此html

Question

我尝试按照在线说明进行操作（许多内容完全相同的文章）https://yourbusiness.azcentral.com/insert-timestamps-tumblr-6892.html

这不起作用

                <div class="main">
                    {block:Posts inlineMediaWidth="700" inlineNestedMediaWidth="700"}
                            <article class="{block:Text}"
                            {block:Date}    {block:NewDayDate} {DayOfWeek}, {Month} {DayOfMonth}, {Year} {/block:NewDayDate} {/block:Date} text       {/block:Text}
                            {block:Photoset}{block:NewDayDate} {DayOfWeek}, {Month} {DayOfMonth}, {Year} {/block:NewDayDate} {/block:Date} photoset   {/block:Photoset}
                            {block:Photo}   {block:NewDayDate} {DayOfWeek}, {Month} {DayOfMonth}, {Year} {/block:NewDayDate} {/block:Date} photo      {/block:Photo}
