Question

What is timestamp? Which are 2 types of timestamps?

Answer 1

Answer:

A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving date and time of day, sometimes accurate to a small fraction of a second. The term derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card.

Answer 2

Dates, times, and timestamps cannot be mixed with one another in expressions. The first of the two formats above is the java.sql.Timestamp format. The year must always have four digits. Months, days, and hours may have one or two digits.
