Converting between time formats

Is there a way to convert time from the year_month_day-hh_mm_ss to timestapm (in milliseconds since 1971) with DateUtils? or some other library..

thanks.

You can use timedelta 

from datetime import timedelta
year = timedelta(days=(2017-1971)*365)#number of days from 1971 to 2017
mili_sec = (year.total_seconds())*1000#you will get total_seconds just mulitply with 1000 to get milliseconds

OUTPUT

1450656000000.0

OR

You wanted difference from a particular date.Ex from 1971-01-01 to 2017-03-16-14:08:10

from datetime import datetime
new_day = datetime.strptime("2017_03_16-14:08:10", "%Y_%m_%d-%H:%M:%S")
old_day = datetime.strptime("1971_01_01-00:00:00", "%Y_%m_%d-%H:%M:%S")
diff_day_milliseconds = ((new_day - old_day).total_seconds())*1000

OUTPUT

1458137290000.0

Have a look at the Python datetime and time modules.

from datetime import datetime
d = datetime.strptime("2017_03_16-14:08:10", "%Y_%m_%d-%H:%M:%S")

This will create a datetime object of d

Then use mktime from Python's time module to get your timestamp

import time
time.mktime(d.timetuple())*1000

The *1000 is required to convert from seconds to milliseconds.

Also, do you mean 1971 or the Unix epoch (Jan 01 1970)?

You can parse the time with strptime, then you can get the time since epoch time in milliseconds by using strftime to format only seconds. Multiply by 1000 to get milliseconds.

converted_time.strftime("%s") * 1000
