This afternoon, towards the end of the day, one of my coworkers asked me for help. There was a PC in the New Zealand office that had run out of disk space because the temp folder was full, and the files in the temp folder had my name all over them.
I went over to his desk as he had remote access to said PC, and we started trying to identify the cause.
After quite a while of working through this, I glanced at the time in the corner of the screen, and immediately panicked when it said 7:04pm.
I was supposed to have left by 5:30pm.
After about 10 seconds of silent panicking, I suddenly realised that this was the time of the New Zealand PC, and they're two hours ahead of us in Sydney.
Stupid time zones...
