There are some cases where time zone information is absolutely critical. For example: When scheduling a video conference that crosses national boundaries.
A few hours ago, Google sent me a reminder about today’s LinuxBarbados meeting. The group meets via video conferencing software over the web. Google’s reminder was confusing because it showed the time without the time zone (screenshot below). LinuxBarbados is based in the Caribbean, and some of the members participate from other time zones.
Google’s automated reminder said
3pm - 4pm with no time zone reference. How confusing! Members of the group received the same automated reminder with the same information, regardless of time zone. A small change, displaying the time as
3pm - 4pm (CST) would solve the problem.
