If you update the SessionLifetime setting in the database. If your company is on the default site 1, it would look like this:
SET [SessionLifetime] = 600
WHERE [SiteId] = 1
In the above update query, we change the SessionLifetime from 480 minutes (8hrs) to 600 minutes (10hrs). That should take care of your needs in regards to this. Just make sure you are applying it to the right site
