What Every Programmer Should know about Time
Apart from Character encoding, time and date is another area, where many programmers struggle, including me. Even senior developers lost between GMT, UTC, day light saving and between leap seconds. Frankly speaking, It's not easy to deal with time zones without making any mistake, then add day light savings and effect of that. Problems becomes worse if you using trial and error method, because you will never able to solve your problem by doing that. There are so many things which can go wrong and there are equal number of misconceptions. Things like, whether date contains time-zone or not can confuse you like hell, converting UNIX time to other time-zone can freak you out, forget about clock synchronization and delays. I hope many of your misconception about time will go away and you will build sound fundamental about Time, by reading this classic article.
