Difference between dates command is not avaliable in enterprise

I want to calculate the bot's runtime. Send the time duration to the business team.

Let's say I started the bot at 9:00 a.m. and ended it at 11:00 a.m. The duration is 120 minutes. While the "Difference between dates" command is available in the community, it does not exist in the enterprise. I checked enterprice 20.11. Is there a reason.
Is there another way to get around that problem?
