Doh, hit sent and realized I miss an argument, the input string to be
matched.
So it would become:
<ogc:Function name="template">
<ogc:PropertyName>myAttribute</ogc:PropertyName>
<ogc:Literal>\d{4}-\d{2}-\d{2}T(\d{2}):\d{2}:\d{2}</ogc:Literal>
<ogc:Literal>{1}</ogc:Literal>
</ogc:Function>
and in cql:
template(myAttribute, '\d{4}-\d{2}-\d{2}T(\d{2}):\d{2}:\d{2}', {1})
cheers
