Your experience is that most GG posts are junk but not 
most Gmail posts.  And yet someone else posted that Gmail 
posts are the junk ones.  So I wonder how accurate these 
evaluations are.

In either case, while there has been some spam and garbage
posts in c.l.p in the past, I haven't seen very many lately.  
And even in the past, they seemed pretty recognizable to me 
and easily skipped over.

As for stupid questions, undesired formatting etc, I seldom
look at the message headers so I never noticed whether they 
are mostly from GG or Gmail.  But then again I never found 
it hard to glance at a post and move on if I didn't want to 
read it.  YMMV.

In <news:mailman.774.1347735926.27098.python-list@python.org>, one of 
the first answers to your question you were pointed to pytz. This module 
does exactly what you ask for:

>>> import datetime
>>> import pytz
>>> greek_date = datetime.datetime.now(pytz.timezone('Europe/Athens'))
>>> greek_date
>>> print(greek_date)

If you do a help(pytz), obviously after having imported pytz, you will 
get some information about the module. At the end of this help, there 
are some attributes listed. One of them is all_timezones. Guess what it 
contains?



Best regards,

Günther




PS: I didn't know pytz yet. But it took me just five minutes of reading 
the datetime documentation and trying pytz.timezone(), to get a working 
example.
So I don't understand, why you didn't follow the proposal of trying 
pytz, but claimed, it wouldn't work.
Can you explain, why ist doesn't work for you rsp. what is the error 
when it doesn't work?

import pytz fails in my webhost unfortunately :(
This module is not supported by hostgator.

	I presume you are able to install your own Python scripts, or you
wouldn't even be able to try the import.

	So far as I can see, pytz is a pure Python package -- no binaries...
You should be able to extract it onto your local development machine,
then copy the entire pytz system from your site-packages to whereever
you install your Python scripts. You might have to tweak (from inside
your script) the pythonpath before doing the import, but it should be
doable.

	If not, then I suggest you study the Python Library reference
section for the datetime module -- in particular the part about using
the tzinfo class, and implement just enough to do your time translation.
Most of pytz is just an implementation of the tzinfo class along with a
database of recognized world timezones and offsets.

In programming, you need attention to details.

My reply didn't use datetime.datetime.now(), it used 
datetime.datetime.utcnow().

datetime.datetime.now() gives the local time (local to the system on 
which it is running).

datetime.datetime.utcnow() gives the UTC (GMT) time, which is the same 
everywhere.

The line should be this:

date = (datetime.datetime.utcnow() + datetime.timedelta(hours=8) 
).strftime('%Y-%m-%d %H:%M:%S')

I've also used '%Y' instead of '%y' because I prefer 4 digits for the year.

Cant it be written more easily as:
 date = (datetime.datetime.utcnow(+2)

i know this is not thhe correct syntax but it just needs a way to add GMT+2 hours since utc=gmt

I've dithered about whether to open this can of worms or let sleeping
dogs lie, and I finally decided to make some metaphor potpourri.

Simple UTC offsets are not the same thing as local time. There are a
variety of other considerations, but the main one is Daylight Robbery
Time, where every government wants to put its own stamp on things by
fiddling with the DST rules a bit. Most places will move their clocks
an hour forward for summer and then back for winter. But!

* Some places are sensible and don't have DST at all (eg
Australia/Queensland, America/Arizona)
* Northern hemisphere summer corresponds to southern hemisphere
winter, and vice versa
* Everyone has a different way of defining the boundaries of summer and winter
* And just to confuse us all, Irish Standard Time is used in summer,
and they *subtract* an hour for winter time!

The only way to handle timezones correctly and keep yourself even
marginally sane is to hand the job on to somebody else. I dodged the
whole issue by letting our Postgres database handle everything for us
(date/time formats, timezones, the lot), and having our internal
systems all just work in UTC. You'll likely find it easiest to do the
same thing with a Python library.

Just don't try to pretend to yourself that Greece uses GMT+2, because
it's not that simple. For one thing, it's currently summer there...

I guess that Double British Summer Time made things twice as difficult?

	I think "hours = 2"... UTC to Athens is two hours... the OP was
trying 8 hours to get from US Central to Greece (and not accounting for
possible daylight savings times)

date = ( datetime.datetime.now() + datetime.timedelta(hours=8) ).strftime( '%y-%m-%d %H:%M:%S')

but iam giving +8 hours which is the time difference between texas, us where the server sits and Greece's time.

cant we somehow tell it to use GMT+2 ?

also it would be nice if datetime.datetime.now(GMT+2) can be used.
