Time Zones are Confusing; I’ll Give You That

So, this is sort of a new one. It doesn’t surprise me, but I’m not sure how to take it.

Me: How late will your sales department be open tonight

Telephone customer service representative at mostly clueless large corporation that I am mostly forced to do business with again despite recent vows to the contrary: Uh… Hmmmm…. We are open every night until 1 am.

Me: Okay. Thanks. Is that central time, eastern time? What time zone?

Rep: Uhh….. Time zone? …. We are open until 1 am!
