For those who work multiple time zones, it's helpful to allow meeting bookings 12-hours ahead of time. Forcing 1-full-day advanced notice to book a meeting unnecessarily reduces availability. AND the alternative (6-hours notice) is simply too short notice (to allow for preparation) when working across multiple time zones.
Visitors current time: 11pm London (UTC-0) === 6pm EST (UTC-5)
Our current time: 6pm EST
It's late in London, but a client or prospect in London wants to book our earliest meeting tomorrow -- i.e., 6am EST. Our current choices are to either...
A) Force 1-day notice and miss the opportunity for an early meeting tomorrow. 😞
B) Allow 6-hours notice and risk missing the meeting because we're not up at midnight to check our calendar. 😞
C) Wake up at 5am EST and scramble for our 6am meeting like a crazy person who doesn't have an automated meeting scheduler. 😞
Adding the 12-hour option will allow us the additional choice of ...
D) Knowing by 6pm EST the day before if we have a 6am meeting scheduled the following day! 🙂
