datetime - Is UNIX time universal -


i did research on internet still confused. unix time universal time gmt/utc or vary place place local time?

i know unix time counted 1st jan, 1970 00:00:00 gmt. when use gettime() function in java (more date d= new date(); long currenttime d.gettime()) getting unix time in milliseconds. if person , person b use same function sitting in 2 different time zones, same result?

now if person , person b use same function sitting in 2 different time zones, same result?

yes, - assuming clocks both "correct" of course.

the java.util.date class wrapper around "the time since unix epoch, in milliseconds". given unix epoch instant in time (not "midnight on january 1st 1970", number of elapsed milliseconds same wherever are. (ignoring relativity , discussion of leap seconds...)

(side-note: @ unix epoch, wasn't midnight in greenwich. 1am, because uk observing bst @ time. that's british standard time, not british summer time - uk @ utc+1 feb 18th 1968 october 31st 1971. more similar trivia, see noda time user guide trivia page.)

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
