在python 3.6中将不同的日期字符串转换为unix时间戳

Question

I have two strings. How can I convert them to UNIX timestamp (eg.: "1284101485")? (Please observe that 1284101485 is not the correct answer for this case.)

I don't care about time zones as long as it is consistent.

string_1_to_convert = 'Tue Jun 25 13:53:58 CEST 2019'   
string_2_to_convert = '2019-06-25 13:53:58'

Answer 1

You can use dateparser

Install:

$ pip install dateparser

Sample code:

import dateparser
from time import mktime

string_1_to_convert = 'Tue Jun 25 13:53:58 CEST 2019'
string_2_to_convert = '2019-06-25 13:53:58'

datetime1 = dateparser.parse(string_1_to_convert)
datetime2 = dateparser.parse(string_2_to_convert)

unix_secs_1 = mktime(datetime1.timetuple())
unix_secs_2 = mktime(datetime2.timetuple())

print(unix_secs_1)
print(unix_secs_2)

Output:

1561492438.0
1561488838.0

The above implementation gives you a consistent response and doesn't give you an error when trying to parse CEST .

Answer 2

you can use .strptime to parse by a format you specify.

try this:

import datetime

string_1_to_convert = 'Tue Jun 25 13:53:58 CEST 2019'
string_2_to_convert = '2019-06-25 13:53:58'

ts1 = datetime.datetime.strptime(string_1_to_convert, "%a %b %d %H:%M:%S %Z %Y").timestamp()
ts2 = datetime.datetime.strptime(string_2_to_convert, "%Y-%m-%d %H:%M:%S").timestamp()

print(ts1)
print(ts2)

NOTICE: the CEST part might be non-portable, as strptime only knows how to parse timezones that appear in time.tzname .
