我无法将python datetime64对象转换为字符串.例如:
t = numpy.datetime64('2012-06-30T20:00:00.000000000-0400')
成:
'2012.07.01' as a string. (note time difference)
我已经尝试将datetime64对象转换为datetimelong然后转换为字符串,但我似乎得到了这个错误:
dt = t.astype(datetime.datetime) #1341100800000000000L
time.ctime(dt)
ValueError: unconvertible time
