Does midnight (00:00) mean the time at the end of day depending on the locale for cron?

Here in France, midnight 00:00 is the end of the day, in English it is the beginning of the day. In a cron table, if a batch is scheduled at 00:00 Friday, it will finish in the morning of Friday. My question is: Does changing the locale and time locale change the definition of midnight? If I configure a server with the french locale, will the batch scheduled at 00:00 Friday finish Saturday morning?
