Hi aaron.b
How about this? Please try to run the following SQL query on the SQL management studio.
select c.ref_num, dateadd(ss,a.time_stamp+32400,'1/1/1970')
from act_log a LEFT JOIN call_req c on a.call_req_id = c.persid
where a.type= 'tr' AND a.description like 'Transfer assignee from%to%ServiceDesk%'
This sample will fetch the incident#(ref_num) that is transfer to the ServiceDesk user as assignee. Please change the 'ServiceDesk' with bold to your id.
Also, the time_stamp field on the act_log table that is stored the activity log has the timestamp as UNIX date. it is necessary for you to set an appropriate value for your timezone at the first line("time_stamp+32400" part).
Just in case, I will attach the discussion about the date conversion as follows.
Convert UTC date to local time
