I work for a small startup that builds software used by people in different timezones. In recent months the company has been trying to improve issues related to timezones, but they are not investing in the training to educate co-workers about timezones.
I believe that it's an essential skill required by people in software development, QA, customer support and client services departments.
As a developer, I have to take the problems they report and implement solutions. Their inability to communicate the problems effectively is having an impact on my job performance. I spend a lot of time in meetings trying to explain how timezones work, whose responsibility it is to fix an issue and explain that value X on date Y should actually be calculated as Z.
I feel that my co-workers could learn more about timezones on their own.
I have gone to the HR department to discuss the challenges as this is a multi-department issue. I made several suggestions including a general company wide training session on timezones, and also asked that timezone questions become a standard question during interviews. None of my recommendations were put into practice.
I am not comfortable with doing training myself on this topic as I would have to train QA, support, etc. etc..
What is the best way to ask on-site coworkers to learn more about timezones?
