How to Tell What Time It Is

Here's a trick for figuring out what time it is in Korea. We're 15 hours ahead of CST, so those of you in Iowa, Illinois, Wisconsin, etc. can just add 3 hours from CST and flip whether it's morning or night. For example, right now it's 5:45 pm in Iowa. That means in Korea it's 8:45 am. Those of you in other time zones can figure it out from there.
