Your JQL query is not actually sorting the results at all. If you want to do that, you will likely need to add in the 'ORDER BY' clause, select a field to sort by, and then a direction (ascending or descending).
If the JQL was in Jira it would look something like this:
assignee=admin AND created>=2018-01-01 AND updated<2018-01-31 AND timespent >0 ORDER BY updated desc
In your case, I'm not sure the exact syntax though since it seems like some of the characters are already getting replaced with + signs and other characters.
