Round each value in aduration大批to the nearest number of seconds less than or equal to that value.

t = hours(8) + minutes(29:31) + seconds(1.23); t.Format ='hh:mm:ss.SS'
t =1x3 duration08:29:01.23 08:30:01.23 08:31:01.23
Y1 = floor(t)
Y1 =1x3 duration08:29:01.00 08:30:01.00 08:31:01.00

Round each value int到最接近的小时数小于或等于该值。

Y2 = floor(t,'hours')
Y2 =1x3 duration08:00:00.00 08:00:00.00 08:00:00.00
