just nak kasi idea.....

contoh nak kira masa dr pkl 5.45 hingga 9.00...<---no ke dua

1st...

tukar nombor ke dua tu dulu....jam tolak 1..minit + 60...


jadi 8.60-5.45 = 3.15

tak pon contoh lain..

3.45 hingga 5.15<---no kedua

tukar dulu..
jam -1..minit +60

jadi 4.75-3.45=1.30 means 1jam 30 minit..

p/s: still kena guna otak sendiri time nak tambah n tolak nombor kedua

untuk memudahkan pengiraan
tukarkan dalam sistem 24 jam dulu

12.00 am - 12.59 am  - 0.00 to 0059
1.00 am - 11. 59 am  -  0100 to 1159
12.00 pm - 12.59 pm - 1200 to 1259
1.00 pm - 11.59 pm - 1300 to 2359


kemudian tolak guna sistem 24 jam...
cth: 9: 15 am hingga 11.15 pm

9.14 am ---> 0915
11.15 pm ---> 2315

2315 - 0915 = 1400

1401 bermassud 14 jam 1 minit
