[02. Elements for expression]
:
You can use the time element to give meaning to time expressions.
For example, if you simply write '2023_01_01', you can clearly tell that it is a date visually, but it is difficult for the system to distinguish whether it is just plain text or a date. Therefore, it is better to use the time element to give meaning to dates, times, etc.
The time element has an attribute called datetime, and you can specify a time or date in an exact format to this attribute so that the system can recognize the specified time or date.
