Cron job not running at specific time, but runs every min - cron

I have developed the project in CodeIgniter (PHP Framework), I have a created model to insert records in the database.
If I set the following cronjob using a cpanel and call it every minute then it works perfectly.
* * * * * wget https://domainname.com/controller_name/function_name
But if I set the cronjob for a specific time, which is supposed to be 2.00 PM every day. Then it is not working.
0 14 * * * wget https://domainname.com/controller_name/function_name

Cron job every minute, specify seconds offset

I configure the cron job in Cpanel, and it works when setting it to * * * * * , every minute.
However I dont want it to execute at the beginning of every minute, I want to specify an offset, like 7 seconds after the start of each minute.
I thought I would specify that by doing
*/7 * * * *
But that doesn't work, I think it executes every 7th minute. There is no setting for "seconds" in cpanel. There is only "Minute Hour Day Month Weekday".
So, is it possible to configure this?
have a look at this
* * * * * ( sleep 7 ; /path/to/executable param1 param2 )

set cronjob time

i was trying to make a code to automatically send mails from a server. I want it to run a php everytime at every hour and 15 minutes and 30 minutes.
Example at 08:15, 08:30, 09:15, 09:30, etc..
Thank you,
Daniel!
How about this?
15-30/15 * * * * * php foo.php
Obviously, replace php foo.php with the command you'd like to run. The 15-30/15 syntax indicates: minutes 15 through 30, with increments of 15. This will make your job run every hour at xx:15 and xx:30.

cronjob not working

I have a strange problem. I have a cron set up to check a database for a given date that is entered. If today's date matches the db recond, it supposed to change a value in a db table.
now, for some reason if the cron is set to go off every minute, it works like a charm. If it's set to a certain time, it doesn't fire at all.
(MYDOMAIN is set to the proper domain. )
works with:
* * * * * php -q /var/www/vhosts/MYDOMAIN.com/httpdocs/admin/scripts/includes/check_date.php
doesn't work with:
40 16 * * * php -q /var/www/vhosts/MYDOMAIN.com/httpdocs/admin/scripts/includes/check_date.php
or any variation of that time
any idea why it wont fire on anything else then every minute?
Check that your system time matches the timezone you are expect it to fire in by running
date
Did you try 59 23 * * * ? try the last minute of the day. Maybe the script only works late in the day ...

Does cronjob timing start from the moment it's created or is it preset?

I'm setting up a cronjob to run every 30 minutes on a Linux server.
When does the 30 minute countdown start? Is it counted from the minute I created the cronjob or is it based on a preset 30 minute schedule?
For example:
If I create a cronjob at 9:32, set to run every 30 minutes, will it run at 9:32, 10:02, 10:32, 11:02...
Or is there a predetermined run time such as it's first run would be 10:00 then 10:30, 11:00, 11:30...
If you create a cron with:
*/30 * * * * /command/to/execute
it is the same as:
0,30 * * * * /command/to/execute
which means it will run twice; once on the hour and then 30 mins past the hour.
It doesn't matter what time you create it.
Another example:
*/29 * * * * /command/to/execute
is the same as:
0,29,58 * * * * /command/to/execute
So the cron will run at 00:00, 00:29, 00:58, 01:00, 01:29, 01:58 and so on.
(You can think of / as division. Every minute (*) is divided by 29...)
