What’s today’s date? What time is it?

Use the CURDATE() , CURTIME() or NOW() functions to get values expressed with respect to the connection time zone. Use UTC_DATE(), UTC_TIME(), or UTC_TIMESTAMP() for values in UTC time.

Some applications need to know the current date or time, such as those that write log records tagged with the current date and time. This kind of information is also useful for date calculations that are performed in relation to the current date, such as finding the first (or last) day of the month, or determining the date for Wednesday of next week.

The current date and time are available through three functions. CURDATE() and CURTIME() return the date and time separately, and NOW() returns them both as a date-and-time value:

mysql>SELECT CURDATE(), CURTIME(), NOW();
+------------+-----------+---------------------+
| CURDATE()  | CURTIME() | NOW()               |
+------------+-----------+---------------------+
| 2006-06-03 | 09:41:50  | 2006-06-03 09:41:50 |
+------------+-----------+---------------------+

CURRENT_DATE and CURRENT_TIME are synonyms for CURDATE() and CURTIME(). CURRENT_TIMESTAMP is a synonym for NOW().

The preceding functions return values for the client’s connection time zone (Setting the Client Time Zone). For values in UTC time, use the UTC_DATE(), UTC_TIME(), or UTC_TIMESTAMP() functions instead.

To obtain subparts of these values (such as the current day of the month or current hour of the day), use the techniques discussed in Extracting Parts of Dates or Times.
