Bash cronjob issue for downloading files

I know how to download all the samples from a SFTP server all at once and using the script mentioned below. 

#download.sh
sshpass -p password sftp [email protected]:/Files/2017-05-05-00.zip  ~/local_machine/2017-05-05/
sshpass -p password sftp [email protected]:/Files/2017-05-05-01.zip  ~/local_machine/2017-05-05/
sshpass -p password sftp [email protected]:/Files/2017-05-05-02.zip  ~/local_machine/2017-05-05/
.................................................................
sshpass -p password sftp [email protected]:/Files/2017-05-05-23.zip  ~/local_machine/2017-05-05

Instead of running the script ( download.sh ) to download all the files at once , How can i download the files on hourly interval. For example , On the above script

The first line in download.sh ( download of 2017-05-05-00.zip) need to happen at 7AM and this is only for the file look up 2017-05-05-00.zip and rest of the lines should not be looked up at.

Second line in download.sh ( download of 2017-05-05-01.zip) need to happen at 8AM and So on till 23rd file.

When one is getting executed , None of the other files shouldn't be looked up.

Not sure how to do this using bash cron job , Any suggestions on how to do this please ?

Try this cronjob with GNU date:

0 * * * * sshpass -p password sftp [email protected]:/Files/$(date +"\%Y-\%m-\%d-\%H" -d "-7 hours").zip $HOME/local_machine/$(date +"\%Y-\%m-\%d" -d "-7 hours")/"

Usually it is necessary to escape % with a \ in a cronjob.
