Thank you for using Mighty Addons and for your kind words.
I just tested the time condition and it’s working fine. The thing with time and the date range is, it detects your server time/date and not your system, and most servers follow the UTC time format.
Can you check and modify your server timezone and date? If not, the easy way is to follow the UTC time rather than your country’s default time zone.
For example, if your country follows the GMT, you can search for UTC to GMT and just follow that timezone.
Let me know, how it goes.
