The duration column has been ignored since the commit https://github.com/discourse/discourse/commit/4af77f1e3854c564c8404e08b83e786fd25a7bfe for topic_timers, we use duration_minutes instead. Also removing the duration key from Topic.set_or_create_timer. The only plugin to use this was discourse-solved, which doesn't use it any longer since https://github.com/discourse/discourse-solved/commit/c722b94a97b9710b9e43b40cd879c0af605085bd
