Hi, you can create a variable in liquid and assign the current date, and then use that in your fetch:
{% assign currentDate = now | date: "yyyyMMddHHmmss" %}
{% assign conditionCache = ' <condition attribute="new_name" operator="ne" value="' | append: currentDate | append: '" />' %}
You can also define the format using the | date filter
This example I am creating a condition and then using in a fetch, as per below:
{% fetchxml myFetch %}
<fetch>
<entity name="new_entityname">
<filter type="and">
{{ conditionCache }}
</filter>
</entity>
</fetch>
{% endfetchxml %}
