Operating times on email notifications

I have created a new email template which includes operating times for any new call logged. However it doesn't display as I would like it. Because the Operating Times Table includes two sets of times per day (i.e. From - To, From - To) but we only have one, then the email shows
08:30 AM - 05:00 PM , none - none (Europe/London)
. Is there a way of removing the second set either from the email or the table itself? And can I also remove the timezone (Europe/London) from the email?

Hi poomonster,

Of course, you can remove the times from the e-mail, or you can specify the working hours taking into account the lunch break.
So 8:30 a.m. - 12:00 p.m., 12:30 p.m. - 5:00 p.m. (Europe / London)

Karslon didn't answer the question asked.
If the service desk does not close for lunch, how do you remove ', none - none'; just need one block of time. Why does it even display none?

Also, If everyone is in the same timezone, can the timezone reference be excluded?
