When your project team is scattered over multiple time zones, just telling each other when something is supposed to happen can become confusing. "I'll call you at 3" just won't do. Which time zone did you mean? AM or PM? Adopting a conventional way of referencing times eliminates confusion and makes life easier for everybody.
If I normally work in Boston, and Jim normally works in San Jose, and Rachel normally works in Austin, we live in three different time zones. When we talk to each other pairwise, and cite specific times to each other, we have to be careful to avoid confusion. I might decide, for example, to always quote my times in the Eastern time zone. And I might even be careful about saying so: "I'll call you at 10 Eastern." When I'm talking to Rachel, she has to subtract three hours to figure out whether 10 Eastern works for her. I have to remember to say "Eastern" and Rachel has to hear it, and remember that Eastern is three hours ahead of her (not behind). If we both do everything right, all is well. Then she has to shift gears when she talks to Jim, because he's in Central.
Adopting a convention about how project team members quote times to each other reduces the chances of confusion. If a project team can pick a time zone that will be the project's time zone, and always cite times in that time zone, life is easier.
There isn't much chance of confusion about time zones in email headers or in software, because most software is aware of the issue and can present times in a variety of formats. The real problem happens in verbal communication and in text that we type into documents and messages. So let's look at how adopting a "Project Time" can save you trouble and reduce confusion.
"Project Time" is the conventional time zone that everyone agrees to use when communicating with project team members. For example, if most of the team is based in the Central Time Zone, it would make sense to quote all times in Central Time. This does require that everyone learn how to convert back and forth between Central Time and the zone they're in. But that's all they have to learn. Since nobody ever quotes a time in Eastern Time, somebody who lives in the Pacific Time Zone will never have to make a conversion from Eastern to Pacific. If you travel to another time zone away from your home base, you'll have to start to make conversions between Central Time and your temporary base. But that's your responsibility, nobody else's.
Having a Project Time helps you avoid having to know where everyone else is, and knowing how to convert the times they quote. All you have to know is where you are. And nobody else has to know where you are. All they have to know is where they are.
Glitches are still possible, even when you decide to have a Project Time. For example, sometimes people work on two or more projects. One project might decide to use Central Time, and another might decide to use Pacific Time. When this happens, the people who work on both projects have to keep straight which is which. To avoid this problem, quote project time by its real name, rather than as "project time." For example, if Project Time is Pacific, say "The conference call is at 10 am Pacific Time," rather than "The conference call is at 10 am Project Time." This makes it easier for people who work multiple projects.
There are a few alternatives to Project Time:
If you use the listeners' time zones, you face several problems:
Using your own time zone instead is also problematic:
Both of these approaches are more likely to lead to confusion than using Project Time.
The US Military has had to deal with this same problem for many years. They long ago adopted what they call "Zulu" time. Essentially, Zulu is the time at 0° of longitude, at the Royal Naval Observatory in Greenwich, UK. Zulu time is actually a time called Universal Time (UTC), if you're interested in the technicalities. If your team is international, and especially if you work with the military or if your team spans the prime meridian, Zulu time is a good choice for Project Time. But if nobody on your team actually uses Zulu, it's probably better to pick the time zone that most people use.
