Measurement Of Time
We use Hours, Minutes and Seconds to Read the time.
In this clock, The hour's hand is on 10 And the minutes hand is on 2. The no. 2 shows 10 minutes.

Pm - Post-Meridian
AM - AM is the Time Between Midnight 12 o'clock Till noon 12 o'clock.

12 Hour Method -

24 Hour Method -
The time in which Am & PM is not written is called time written by 24 hour method.
For Ex. 22:10
Remember This -
12 = 00 / 24
1 = 13
2 = 14
3 = 15
4 = 16
5 = 17
6 = 18
7 = 19
8 = 20
9 = 21
10 = 22
11 = 23
Hence, this clock shows the Time 10 :10.

Operation on Time
For Ex. 12:06:34 + 3:55:45
12:06:34
+ 3:55:45
15:61:79
= 16:02:19
Its very simple. Just as the Simple Addition !
Ex. 2. What is 4:10 - 1:35 ?
Subtract the Hours: 4-1 = 3
Subtract the Minutes: 10-35 = -25
The minutes are less than 0, so add 60 to Minutes (-25+60 = 60-25 = 35 Minutes) and subtract 1 from Hours (3-1 = 2 Hours) ... answer is 2:35
You can do in the Same Way With the Seconds Also.
