2) What is timestamping, and what are the types of timestamping

Meaning: A timestamp is the current time of an event that is recorded by a computer. Through mechanisms such as the Network Time Protocol ( NTP ), a computer maintains accurate current time, calibrated to minute fractions of a second.

Example: The TIMESTAMP data type is used for values that contain both date and time parts. TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC. A DATETIME or TIMESTAMP value can include a trailing fractional seconds part in up to microseconds (6 digits) precision.
