Timezone converter

Another useful script which helps in day-to-day routine. (it takes all data from timeanddate.com)

What should be installed :

Of course Python3
Script:

wget --no-check-certificate --content-disposition https://raw.githubusercontent.com/apalii/timezone/master/timezone.py

ALso you need pip for python3 - it is command line tool which can install/update/uninstall Python packages.

sudo apt-get install python3-pip

Requests module

sudo pip3 install requests

beautifulsoup4 module

sudo pip3 install beautifulsoup4

On my machine:

echo -e "$(python -V)$(python3 -V)\n$(pip list|egrep -i 'req|beau|argp')"

Python 2.7.6
Python 3.4.0
argparse (1.2.1)
beautifulsoup4 (4.3.2)
requests (2.2.1)

Example :

Usecase : You should schedule some maintenance on the production installation in different time zone. Solution: Let's imagine that some restarts should be performed on 5th of Dec at 23-00 (New-York TZ). So run the following:

python3 timezone.py -c new-york -d 20141205 -t 23

where 
   -c - city
   -d - date in format yyymmdd
   -t - time hhmmss

Output will be the following (just copy/paste in TT):

updatedb script

If you run it you will download 4119 pages from timeanddate.com and create new databases with IDs of the cities. Some unusefull cities will be skipped :

ignored = [1440, 3875, 367] # UTC, Zulu, Kyiv
ignored.extend(range(3878, 3902)) # Alpha, Beta, etc.
ignored.extend(range(3903, 3929)) # UTC times
if i in ignored:
    continue

It takes about 2 hours (:
