Converting epoch to h:mm within MySQL Query

Simply query starts like...

---
SELECT apps_zapata_walks.id, apps_zapata_walks.walker_fname, apps_zapata_walks.walker_lname, apps_zapata_walks.walker_email, mdl_user.firstname as TeacherFirstName, mdl_user.lastname as TeacherLastName, mdl_user.email as TeacherEmail, mdl_groups.`name` as CampusName, apps_zapata_walks.co_teacher, apps_zapata_walks.date_of_walk, apps_zapata_walks.auto_time_in, apps_zapata_walks.auto_time_out,
---

How can I format the apps_zapata_walks.auto_time_in as hh:m within the query?

something like...

date('gia',apps_zapata_walks.auto_time_in) ???

Of course I doubt that would work but I am having trouble finding out what will.

Thank you in advance!

Use this, instead of the plain column name:

EXTRACT(HOUR_MINUTE FROM apps_zapata_walks.auto_time_in) AS auto_time_hh_mm

Notice you have to alias it like I did.

epoch is in UTC, you may want to convert the time into a certain time zone.

http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html
FROM_UNIXTIME() fits better to the epoch unix timestamp.

SELECT FROM_UNIXTIME(auto_time_in,'%H:%i') as auto_time_hh_mm

Open in new window


The reference also says:
The value is expressed in the current time zone
That is you get HH:MM in the time zone of the MySQL Server.

And you can use date(), but not within the query, mysql runs mysql functions, not php functions. But you can query the unix timestamp and when displaying it can use the PHP date() with the data fetched unchanged.

Bye, Olaf.

did you try

 select DATE_FORMAT(apps_zapata_walks.auto_time_in,"%h:%i")
