For some offices, tech like Teams/Outlook would certainly help, sure. But the majority of offices aren't using that. But even still, people would do it regardless. Say you're going on vacation and want to know when daylight hours are, you'd still be doing the same thing. Timezones may be annoying, but they ultimately make sense. We have a universal time for the planet powering the system, there's really no reason to change it, in my opinion.
