I once scheduled an interview with someone on the West coast (I'm on the east coast). I emailed him in the morning "How about 4 o'clock?" That afternoon around 2 I checked my email again and got his response "great, you can call me at 1." I freaked out for a second thinking I had missed the appointment, only to realize he meant 1 pm his time == 4 pm my time.
