mktime() output not the same as the date utility
Hi,
I can't figure out from the man pages why
mktime() is giving a different result than date -f.
Both strptime and mktime are supposed to use the
local timezone, as does date.
The output of date is correct; mktime() is an hour later.
What am I missing here?
Thanks,
m

In case you are interested, I've patched the re_format man page with this example. I had read it, and it says :print: is the "name of the character class."

How to delete non-ASCII chars in file
I have a text file that includes some non-ASCII characters For example, opening the file in vi shows lines like this: 'easth_0.541716776378' 0 \xe2\x80\x98dire' 2 Is there a command-line tool I can use to delete these characters? I tried: cat f | tr -cd [:print:] but this removes the newlines. I also tried cat f | sed "s/[^:print:]//g" but it didn't remove the characters.
