30 * cron.php - this file is an entry point to execute scheduled jobs in Time Tracker.
31 * It must be called externally (for example, from the system cron or task scheduler).
33 * Internally, we store scheduled jobs in tt_cron table in db. The cron_spec field is in cron format.
34 * Along with it, we store last and next timestamps for jobs, we use them as an execute condition.
36 * Although cron_spec follows 5-field cron specification precisely, actual job timing depends on
37 * how often cron.php is called. For example, an hourly ping will execute jobs no more than once
38 * each hour, even if they are due more often. Configure whatever calls this file accordingly.
