The `time` module in Python is used to calculate elapsed time in seconds.
# Syntax
The general syntax is:
1. Import the `time` module
```python
import time
```
2. Use the `time` module functions

| **Function Name**  |**Description**   |   
|---|---|
|`time.time()`| calculates the time elapsed from 1917 (the beginning of time in computers)  in seconds   |   
|`time.asctime()`| calculates the current time  |   
|`time.gmtime()`  |calculates the greenwich mean time   |  
|`time.sleep(n)`| `n` is the number of seconds for which the program goes to sleep

import time
print(time.time())
print("Current time:",time.asctime())
print("Greenwich mean time:",time.gmtime())
# To access one particular value from Greenwich Mean Time 
value=time.gmtime()
print(value[2])

# Example 1: Calculate the time for code execution
Using the `time` module it is possible to calculate the time it takes for a piece of code to execute.

Take two time values, one at the start of your code execution and another at the end. By subtracting the second value from the first, you will get the execution time of the code. 
The following code shows how it can be done:

import time
start= time.time()
a=1
b=2
c=a+b
print(c)
stop=time.time()
print(stop-start)


# Example 2: Calculate the time for code execution using `sleep` method
The code stops executing for `n` number of seconds passed as a parameter to `time.sleep`.
The following code shows how it can be done:

import time
start= time.time()
a=1
b=2
c=a+b
print(c)
time.sleep(2)
stop=time.time()
print(stop-start)


What is the Python time module?

The time module in Python calculates elapsed time, current time, Greenwich Mean Time, and allows pausing code execution.

Function Name	Description
`time.time()`	calculates the time elapsed from 1917 (the beginning of time in computers) in seconds
`time.asctime()`	calculates the current time
`time.gmtime()`	calculates the greenwich mean time
`time.sleep(n)`	`n` is the number of seconds for which the program goes to sleep
