Select time, SUM(on_cnt),SUM(off_cnt) FROM 
(select time,[on] as on_cnt,[off] as off_cnt from table1 
pivot 
(
count(Status) 
for Status in ([on],[off]) 
) as p) as st 
GROUP BY time

Answer 2

Как насчет чего-то вроде

SELECT 
[Time], 
SUM(CASE WHEN [Status] = 'On' THEN 1 ELSE 0 END) CntON, 
SUM(CASE WHEN [Status] = 'Off' THEN 1 ELSE 0 END) CntOff 
FROM Table 
GROUP BY [Time]
