time.mktime()
method of
Time moduleis used to convert a
time.struct_timeobject or a tuple containing 9 elements corresponding to
time.struct_timeobject to time in seconds passed since epoch in local time. This method is the inverse function of
time.localtime()
which converts the time expressed in seconds since the epoch to a
time.struct_timeobject in local time. Following are the values present in time.struct_time object:
Index Attribute Values 0 tm_year (for example, 1993) 1 tm_mon range [1, 12] 2 tm_mday range [1, 31] 3 tm_hour range [0, 23] 4 tm_min range [0, 59] 5 tm_sec range [0, 61] 6 tm_wday range [0, 6], Monday is 0 7 tm_yday range [1, 366] 8 tm_isdst 0, 1 or -1 N/A tm_zone abbreviation of timezone name N/A tm_gmtoff offset east of UTC in seconds Note:The epoch is the point where the time starts and is platform dependent. On Windows and most Unix systems, the epoch is January 1, 1970, 00:00:00 (UTC) and leap seconds are not counted towards the time in seconds since the epoch. To check what the epoch is on a given platform we can use time.gmtime(0).
Syntax: time.mktime(t) Parameter: t : A time.struct_time object or a tuple containing 9 elements corresponding to time.struct_time object Return type: This method returns a float value which represents the time expressed in seconds since the epoch.Code #1:
Use of
time.mktime()
method
Python3
# Python program to explain time.mktime() method
# importing time module
import time
# time.gmtime() method will returns
# a time.struct_time object in UTC
# for the time expressed in seconds
# since the epoch
seconds = 1000000
obj1 = time.gmtime(seconds)
# Print time.struct_time object (in UTC)
print(obj1)
# Convert the time.struct_time
# object to local time expressed in
# seconds since the epoch
# using time.mktime() method
time_sec = time.mktime(obj1)
# Print the local time in seconds
print("\nLocal time (in seconds):", time_sec)
# time.strptime() method parse
# a string representing a time
# according to the given format
# and returns a time.struct_time object
# Time string
t = "14 Sep 2019 10:50:00"
# Parse the time string using
# time.strptime() method
obj2 = time.strptime(t, "% d % b % Y % H:% M:% S")
# Convert the time.struct_time
# object to local time expressed in
# seconds since the epoch
# using time.mktime() method
time_sec = time.mktime(obj2)
# Print the local time in seconds
print("\nLocal time (in seconds):", time_sec)
Output:
time.struct_time(tm_year=1970, tm_mon=1, tm_mday=12, tm_hour=13, tm_min=46, tm_sec=40, tm_wday=0, tm_yday=12, tm_isdst=0) Local time (in seconds): 980200.0 Local time (in seconds): 1568438400.0Code #2:
If parameter is a tuple
Python3
# Python program to explain time.mktime() method
# importing time module
import time
# A tuple containing 9 elements
# corresponding to time.struct_time object
# for example: consider the below object
# time.struct_time(tm_year = 2019, tm_mon = 9, tm_mday = 13,
# tm_hour = 1, tm_min = 30, tm_sec = 26, tm_wday = 4,
# tm_yday = 256, tm_isdst = 0)
# Tuple corresponding to above
# time.struct_time object will be
tup = (2019, 9, 13, 1, 30, 26, 4, 256, 0)
# Convert the above specified tuple
# to local time expressed in seconds
# since the epoch
# using time.mktime() method
time_sec = time.mktime(tup)
# Print the time
print("Local Time (in seconds since the epoch):", time_sec)
Output:
Local Time (in seconds since the epoch): 1568318426.0Code #3:
To show
time.mktime()
method is inverse function of
time.localtime()
method
Python3
# Python program to explain time.mktime() method
# importing time module
import time
# Get the current time
# expressed in seconds
# since the epoch using
# time.time() method
curr_time = time.time()
# Print the value
# returned by time.time() method
print("Current time (in seconds since the epoch):", curr_time)
# Convert the time expressed in seconds
# since the epoch to
# a time.struct_time object
# in local time using
# time.localtime() method
obj = time.localtime(curr_time)
# Print the time.struct_time object
print("\ntime.struct_time object:")
print(obj, "\n")
# Convert the time.struct_time object
# back to the time expressed
# in seconds since the epoch
# in local time using
# time.mktime() method
time_sec = time.mktime(obj)
# Print the time
print("Time (in seconds since the epoch):", time_sec)
Output:
Current time (in seconds since the epoch): 1568318426.2286296 time.struct_time object: time.struct_time(tm_year=2019, tm_mon=9, tm_mday=13, tm_hour=1, tm_min=30, tm_sec=26, tm_wday=4, tm_yday=256, tm_isdst=0) Time (in seconds since the epoch): 1568318426.0References: https://docs.python.org/3/library/time.html#time.mktime
