Examples

创建一个时间戳对象：

>>> ts = pd.Timestamp('2020-03-14T15:32:52.192548651', tz='UTC')
>>> ts
Timestamp('2020-03-14 15:32:52.192548651+0000', tz='UTC')

替换年份和小时：

>>> ts.replace(year=1999, hour=10)
Timestamp('1999-03-14 10:32:52.192548651+0000', tz='UTC')

替换时区（非转换）：

>>> import pytz
>>> ts.replace(tzinfo=pytz.timezone('US/Pacific'))
Timestamp('2020-03-14 15:32:52.192548651-0700', tz='US/Pacific')

pd.NaT 的类似用法：

>>> pd.NaT.replace(tzinfo=pytz.timezone('US/Pacific'))
NaT
