Java Dates ClassDescriptionLocalDateRepresents a date (year, month, day (yyyy-MM-dd))LocalTimeRepresents a time (hour, minute, second and nanoseconds (HH-mm-ss-ns))LocalDateTimeRepresents both a date and a time (yyyy-MM-dd-HH-mm-ss-ns)DateTimeFormatterFormatter for displaying and parsing date-time objects

Datetime. now() method contains the year, month, day, hour, minute, second, and microsecond (expressed as YYYY-MM-DD hh:mm:ss. ffffff ). It also accepts an optional time_zone parameter, which is set to None by default.

In MySQL, we can insert the current date and time automatically to a column on inserting the values in another column by declaring that column as DEFAULT CURRENT_TIMESTAMP.

Datetime.date - represents a date (year, month, and day) without a time. datetime.time - represents a time (hour, minute, second, and microsecond) without a date.

The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in ' YYYY-MM-DD hh:mm:ss ' format. The supported range is '1000-01-01 :00' to '9999-12-31 :59' . The TIMESTAMP data type is used for values that contain both date and time parts.

MySQL recognizes DATETIME and TIMESTAMP values in these formats: As a string in either ' YYYY-MM-DD hh:mm:ss ' or ' YY-MM-DD hh:mm:ss ' format. ... As a string with no delimiters in either ' YYYYMMDDhhmmss ' or ' YYMMDDhhmmss ' format, provided that the string makes sense as a date.

MySQL uses yyyy-mm-dd format for storing a date value. This format is fixed and it is not possible to change it. For example, you may prefer to use mm-dd-yyyy format but you can't. Instead, you follow the standard date format and use the DATE_FORMAT function to format the date the way you want.
