DevPress

Enables WooCommerce product sale scheduling to the day, hour and minute.
This extends the default WooCommerce functionality which only offers product sale scheduling to the day (in 24 hour increments). This plugin adds a field for hour and minute, so that sales can be scheduled to start and end at a more precise time.
This extension is especially helpful for shops that operate in a country with multiple timezones (like the United States) that want to offer a one day sale across timezones. For those shops, a sale can start at midnight in one timezone and end at midnight in another timezone- allowing a 27 hour sale (or other arbitrary period).
