Problem
You need to account for time zones, Daylight Saving Time, and leap years or seconds.
Solution
Don’t. This is a lot trickier than it sounds. Leave it to code that’s already been in use and debugged for years, and just use a tool that can handle your needs. Odds are high that one of the other recipes in this chapter has covered what you need, probably using GNU date. If not, there is almost certainly another tool out there that can do the job.
