## 4. Miscellaneous problems

## 4.1 Time zone

Denmark is placed in the Central European Time zone (CET or MET,) which (in the winter) is equivalent to Greenwich Mean Time plus 1 (GMT+1.) You set the time zone on a Linux system by making a symbolic link between `/usr/lib/zoneinfo/localtime` and the file in `/usr/lib/zoneinfo/` with a name corresponding to your zone or country. Danes will want to execute one of the commands

    ln -sf /usr/lib/zoneinfo/MET /etc/localtime

or

    ln -sf /usr/lib/zoneinfo/Europe/Copenhagen /etc/localtime

This automatically sets Daylight Saving Time (GMT+2) in the summer.

You synchronize the system time with the CMOS clock by issuing the command `clock` as root. If your CMOS clock is set to GMT (a.k.a. UTC --- the standard on proper Unix systems) use

    clock -u -s

or if your CMOS clock is set to local time use

    clock -s

## 4.2 A4 papersize

- `ghostscript`: Add the command line option `-sPAPERSIZE=a4`.
- `ghostview`: Define the following Xresource:

      Ghostview.pageMedia:  A4

- `TeX/LaTeX`, `dvips`, `xdvi`: See the entry for TeX/LaTeX in section International character sets in specific applications.

## 4.3 Text file formats for other platforms

You can translate files between an ISO-8859-1 formatted text file and e.g. a DOS text file using codepage 850 with the `recode` package. A DOS file called `foo.txt` would be translated into a proper Unix file with the command

    recode cp850:latin1 foo.txt

`recode` is available as `recode-3.4.tar.gz` from all mirrors of the GNU archive.
