Yes the cron time is correct. 

1 0 * * * /mydir/myscript

should be your cron entry.

Each cron entry consists of six fields, in the following order:

minute(s) hour(s) day(s) month(s) weekday(s) command(s)
 0-59      0-23    1-31    1-12     0-6

Let's get the definitions straight: cron is a daemon that is designed to run continuously and execute commands at specified intervals when you tell it to.

To do that, it needs two things: an interval and a command.

Your example has a valid interval, but is missing a command to execute one minute after midnight:

1 0 * * * * /path/to/executable/or/script/here
