Ruby这边基本上就是通过Date和Time来解决这问题。有Date::today和Time::now，另外就是 Date::strftime和Time::strftime。不过Ruby在对中文的支持上也还是不够好啊（还是说我没弄清楚该怎 么用？），要是能指定Locale就好了。
Time实例里有完整的时间信息，从年份到秒都有记录。而Date只记录到天，并且有更加严格的检查（ 以及对Gregorian历法的不同支持等）。
Perl：
Perl的话，装上Date::Format会方便很多。以往的做法是通过localtime()获取毫秒的时间，然后通过 Date::Format提供的time2str()函数来转换成自定义的格式。不过从Perl6开始提供了date()和utcdate() 来获取当前时间。 |
