When you read a date or time from a text file, user input, or a database, you are likely to get the date information as a string. It is helpful to convert the string to a datetime object since it will allow you to do more advanced functions. In today’s article, I will discuss ...

Convert one time zone to another, which is the bulk of the program Add custom time zones which can be saved to a file for later use I wrote this software in order to practice using the Python programming language. I made a simple class that stores the idea of Time in hours, minutes,...
pytz.timezone('US/Eastern') #利用时区名,获取时区对象 print(ts.index.tz) #ts的索引中没有时区信息 #可以在创建数据集的时候通过 tz=‘UTC’来创建 ts_utc=ts.tz_localize('UTC') #本地化时区 ts_utc.tz_convert('US/Eastern') #本地化后的时间序列才能被转换成别的时区 ...
跟时间序列和日期范围差不多,独立的Timestamp对象也能被从单纯型(naive)本地化为时区意识型(time zone-aware),并从一个时区转换到另一个时区:In [128]: stamp = pd.Timestamp('2011-03-12 04:00') In [129]: stamp_utc = stamp.tz_localize('utc') In [130]: stamp_utc.tz_convert('America/...
时区意识型Timestamp对象在内部保存了一个UTC时间戳值(自UNIX纪元(1970年1月1日)算起的纳秒数)。这个UTC值在时区转换过程中是不会发生变化的: In [133]: stamp_utc.value Out[133]: 1299902400000000000 In [134]: stamp_utc.tz_convert('America/New_York').value Out[134]: 1299902400000000000 当使用panda...
ValueError: Excel does not support datetimes with timezones. Please ensure that datetimes are timezone unaware before writing to Excel. 我已经尝试过几种方法,例如“dt.tz_convert”、replace(tzinfo=None) 以及我在这里和周围找到的其他解决方案。
