我正在尝试像"Sat, 11/01/09 8:00PM EST"在Python中那样解析时间戳字符串,但是在寻找一种可以处理缩写时区的解决方案时遇到了麻烦。
"Sat, 11/01/09 8:00PM EST"
我正在使用dateutil的parse()功能,但无法解析时区。是否有捷径可寻?
dateutil
parse()
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:
parser.parse()
{'EST': -5*3600}
>>> import dateutil.parser as dp >>> s = 'Sat, 11/01/09 8:00PM' >>> for tz_code in ('PST','PDT','MST','MDT','CST','CDT','EST','EDT'): >>> dt = s+' '+tz_code >>> print dt, '=', dp.parse(dt, tzinfos=tzd) Sat, 11/01/09 8:00PM PST = 2009-11-01 20:00:00-08:00 Sat, 11/01/09 8:00PM PDT = 2009-11-01 20:00:00-07:00 Sat, 11/01/09 8:00PM MST = 2009-11-01 20:00:00-07:00 Sat, 11/01/09 8:00PM MDT = 2009-11-01 20:00:00-06:00 Sat, 11/01/09 8:00PM CST = 2009-11-01 20:00:00-06:00 Sat, 11/01/09 8:00PM CDT = 2009-11-01 20:00:00-05:00 Sat, 11/01/09 8:00PM EST = 2009-11-01 20:00:00-05:00 Sat, 11/01/09 8:00PM EDT = 2009-11-01 20:00:00-04:00
关于的内容tzinfos,这是我如何填充我的内容:
