   {$vo['recstart']|date="Y-m-d",###}
  

How to output

HTML code

   1970-01-01 

Why? Please ....

------ Solution --------------------
No, you can fix it.
------ Solution --------------------
Is the date () function so used? Not date ("Y-m-d H: I: s?
------ Solution --------------------
{$ Vo ['recstart']}
What is output?
------ Solution --------------------
The value of $ vo ['recstart'] is null or 0, resulting in the output time being 1970-01-01.
