The mktime
function in Python's time
module converts a struct_time
object representing local time to a time expressed in seconds since the Epoch. This function is useful for converting structured time data back into a timestamp.

Introduction
The mktime
function in Python's time
module converts a struct_time
object, which represents local time, into a floating-point number of seconds since the Epoch. This is useful for applications that need to convert human-readable time formats back into timestamps.
mktime Function Syntax
Here is how you use the mktime
function:
import time
time.mktime(t)
Parameters:
t
: Astruct_time
object representing local time.
Returns:
- A floating-point number representing the time in seconds since the Epoch.
Examples
Basic Usage
Here is an example of how to use mktime
.
Example
import time
# Creating a struct_time object representing a specific local time
local_time = time.struct_time((2021, 8, 17, 15, 43, 6, 1, 229, 1))
# Converting struct_time to seconds since the Epoch
time_in_seconds = time.mktime(local_time)
print("Time in seconds since the Epoch:", time_in_seconds)
Output:
Time in seconds since the Epoch: 1629195186.0
Converting Current Local Time
This example shows how to convert the current local time to a timestamp using mktime
.
Example
import time
# Getting the current local time as a struct_time object
current_local_time = time.localtime()
# Converting current local time to seconds since the Epoch
current_time_in_seconds = time.mktime(current_local_time)
print("Current time in seconds since the Epoch:", current_time_in_seconds)
Output:
Current time in seconds since the Epoch: 1721747015.0
Real-World Use Case
Adjusting and Storing Timestamps
In real-world applications, the mktime
function can be used to adjust structured local time data and convert it back to a timestamp for storage or further processing.
Example
import time
def adjust_time(year, month, day, hour, minute, second):
# Create a struct_time object with the given parameters
adjusted_time = time.struct_time((year, month, day, hour, minute, second, 0, 0, -1))
# Convert the struct_time object to seconds since the Epoch
timestamp = time.mktime(adjusted_time)
return timestamp
# Example usage
timestamp = adjust_time(2021, 8, 17, 15, 43, 6)
print("Adjusted time in seconds since the Epoch:", timestamp)
Output:
Adjusted time in seconds since the Epoch: 1629195186.0
Conclusion
The mktime
function converts a struct_time
object representing local time into seconds since the Epoch, making it useful for converting structured time data back into timestamps.
