select _t, date_diff('second', from_iso8601_timestamp(_ts), SELECT from_iso8601_timestamp(f._ts) from logs f 
              where f._t = 'timespent'
               and f.dt = '2016-04-09'
               and f.uid = 'd2de01a1-8f78-49ce-a065-276c0c24661b'
               order by _ts)
from logs d
where _t = 'timespent'
and dt = '2016-04-09'
and uid = 'd2de01a1-8f78-49ce-a065-276c0c24661b'

解決方法は？

あなたが欲しいのは lag() :

select _t,
       date_diff('second', from_iso8601_timestamp(_ts),
                 lag(from_iso8601_timestamp(f._ts)) over (partition by uid order by dt)
                )
from logs d
where _t = 'timespent' and dt = '2016-04-09' and
      uid = 'd2de01a1-8f78-49ce-a065-276c0c24661b'
order by _ts;
