Some Functions in the time Module
| Function | Description |
|---|---|
| asctime([tuple]) | Converts time tuple to a string |
| localtime([secs]) | Converts seconds to a date tuple, local time |
| mktime(tuple) | Converts time tuple to local time |
| sleep(secs) | Sleeps (does nothing) for secs seconds |
| strptime(string[, format]) | Parses a string into a time tuple |
| time() | Current time (seconds since the epoch, UTC) |
Use time structure
import time# from ww w . j a v a 2 s. c o m
gmt = time.gmtime(time.time())
fmt = '%a, %d %b %Y %H:%M:%S GMT'
str = time.strftime(fmt, gmt)
hdr = 'Date: ' + str
print hdr
The code above generates the following result.
time.asctime
The function time.asctime formats the current time as a string, such as
import time
print time.asctime()
The code above generates the following result.
time.time()
time.time() returns the current system time.
import time
print time.time()
The code above generates the following result.
time.localtime(secs)
time.localtime(secs) returns the time in the form of (year, month,
day, hour, minute, second, day of week, day of year, daylight savings).
import time# w ww.j a va2s . c om
print time.localtime()
t = time.localtime()
print t
print t[3]
print t[4]
print t[5]
The code above generates the following result.
time.ctime(secs)
time.ctime(secs) returns the time, specified by secs since the UTC,
as a formatted, printable string.
import time
print time.ctime()
The code above generates the following result.
time.clock()
time.clock() returns the current CPU time as a floating-point
number that can be used for various timing functions.
import time
print time.clock()
The code above generates the following result.
mktime
from random import *
from time import *
# w ww . j a v a 2 s .c o m
date1 = (2005, 1, 1, 0, 0, 0, -1, -1, -1)
time1 = mktime(date1)
date2 = (2006, 1, 1, 0, 0, 0, -1, -1, -1)
time2 = mktime(date2)
random_time = uniform(time1, time2)
print asctime(localtime(random_time))
The code above generates the following result.
time.strftime
You can print the time values using the strftime() method.
import time
print time.strftime("%I:%M")
The code above generates the following result.
time.sleep
time.sleep(sec) forces the current process to sleep for the number
of seconds specified by the floating-point number secs.
import time# ww w . j a v a2 s . c o m
for x in range(3):
print "The time is now", time.asctime()
print "Now sleeping for 2 seconds..."
time.sleep(2)
The code above generates the following result.
