Question

Design the format of the packet with which we want to transmit the current time with an accuracy of milliseconds. Are there more ways to design such a format?

Answer 1

Solution: Metadata is a very important element while transmitting the messages over the communication link. Metadata is nothing but the information about the information such as the time at which the data is generated, the place at which the data is actually generated, etc. It is important in order to efficiently track the place as well as the time of the origination of a message if in case it is required. Now, coming to the question, the current time can be embedded with the message by using a suitable time format in accordance with the timezone that suits that particular place. Some of the famous timestamp formats are given down-below:

1. Time of the Day: 01:02:03.123456
2. Date and Time of the Day: 1970-01-01 01:02:03.182446
3. Seconds Since Previous Displayed Packet: 1.103759
4. Seconds Since Beginning of Capture: 123.123456
5. Seconds Since Previous Captured Packet: 1.123456

Any of the among formats can be used for the effective representation of the time as almost all of them has a precise representation till the 10^-6 part of the second.
