在Python中解析带有时区缩写名称的日期时间字符串？

在Python中解析带有时区缩写名称的日期/时间字符串？

dateutil的

parser.parse()

接受作为关键字参数tzinfos的类型的字典

{'EST': -5*3600}

（即，区域名称匹配GMT以秒偏移量）。因此，假设我们有，我们可以这样做：

>>> import dateutil.parser as dp>>> s = 'Sat, 11/01/09 8:00PM'>>> for tz_pre in ('PST','PDT','MST','MDT','CST','CDT','EST','EDT'):>>>     dt = s+' '+tz_pre>>>     print dt, '=', dp.parse(dt, tzinfos=tzd)Sat, 11/01/09 8:00PM PST = 2009-11-01 20:00:00-08:00Sat, 11/01/09 8:00PM PDT = 2009-11-01 20:00:00-07:00Sat, 11/01/09 8:00PM MST = 2009-11-01 20:00:00-07:00Sat, 11/01/09 8:00PM MDT = 2009-11-01 20:00:00-06:00Sat, 11/01/09 8:00PM CST = 2009-11-01 20:00:00-06:00Sat, 11/01/09 8:00PM CDT = 2009-11-01 20:00:00-05:00Sat, 11/01/09 8:00PM EST = 2009-11-01 20:00:00-05:00Sat, 11/01/09 8:00PM EDT = 2009-11-01 20:00:00-04:00
