计算两个时间相距的分秒数

t1 LIKE sy-uzeit ,
t2 LIKE sy-uzeit .
DATA sec TYPE i.
PERFORM get_second USING d1 d2 t1 t2 sec.
WRITE sec.

FORM get_second USING d1 d2 t1 t2 second.
DATA: days TYPE i,
tint TYPE i.
IF d2 GE d1.
days = d2 - d1.
tint = t2 - t1.
second = ( days * 24 * 60 * 60 ) + tint .
ELSE.
second = 0.
