You're already familiar with Pacific Standard Time, Central Standard Time and Eastern Standard Time. What you may not be acquainted with is Agency Standard Time.
It isn't tracked on a clock or a calendar. In fact, it's barely tracked at all (except for freelancer hours - those are tracked very carefully). Agency Standard Time redefines the whole time-we'll start when we're ready continuum.
In agency time, meetings are scheduled at lunch and Fridays at five. One hour meetings take two-and-a-half hours. Or fifteen minutes. Weekends are yours, unless they're not. Up is down, black is white, night is day. In agencies, time is like a gas - ever expanding to fill the space it occupies. And since gas is mostly hot air, well, you see where I'm going.
Oddly enough, the ability to carve time out for golf with the client, trips to Cannes or SXSW and filling out award entry forms from the One Show to the Effies are remarkably unaffected.
Unlike the ability to blow smoke, or convince the client "this is exactly what Apple would do..." time simply isn't a respected commodity at ad agencies.
Well, at least yours isn't.
