Date and time entity recognition

Github address: https://github.com/danan0755/time_ner

1. If only the date is entered, only the date will be returned, not the time.

2. Only enter the time, the default date is today

3. Due to business needs, if the user inputs "morning, noon, afternoon, evening", etc. that do not include specific times, timetype will be returned, corresponding to -2, -3, -4

tn = TimeNormalizer()
timeBase = arrow.now()

res = tn.parse(target=u'2013年二月二十八日下午四点三十分二十九秒', timeBase=timeBase) # target为待分析语句，timeBase为基准时间默认是当前时间 print(res) {"type": "timespan", "timetype": 0, "timespan": ["2013-02-28 16:30:29"]}

res = tn.parse(target=u'下午3点到5点') 
print(res) 
#{"type": "timespan", "timespan": ["2020-09-05 15:00:00", "2020-09-05 17:00:00"]}

print(res)
