tztab for Brazil??

[Bob Fraser]

Does anybody have a tztab for San Paulo Brazil.

Any help would be appreciated.

Also what would be the tz variable setting.

I've not seen one specific to BR, but this site should have enough info for you to "roll your own" changes if need be.

Note the admonishion that "these rules change often.....". Appears that the timezones are BRT / BRST

"man 4 tztab" has details on the file layout if you choose to go that route

This is what I have tried:
# horario verao
BEST3BEDT
0 0 15-21 2 2003 0 BEST3
0 0 18-24 10 2003 0 BEDT2
0 0 14-20 2 2004 0 BEST3
0 0 1-2 11 2004 2 BEDT2
0 0 20-21 2 2005 0 BEST3
0 0 16-17 10 2005 0 BEDTA
0 0 18-19 2 2006 0 BEST3
0 0 4-5 11 2006 0 BEDT2
0 0 24-25 2 2007 0 BEST3
0 0 13-14 10 2007 0 BEDT2
0 0 16-17 2 2008 0 BEST3

This is what I get:

# TZ=BEST3BEDT date;date -u
Thu Apr 24 17:25:26 BEDT 2008
Thu Apr 24 19:25:26 UTC 2008

This is wrong. S/B UTC - 3

Any suggestions
thanks

It appears Brazil is in the southern hemisphere, you should look at Australia.

The standard way of doing this is to list all of the start times, then list all of the end times. Not sort by year.

Typo.

Where is your entry for start of DST for 2008?

Try both entries for 2008. Also try Clay's dst.pl script:

This works:
BEST3BEDT
0 0 15-21 10 2003 0 BEDT2
0 0 01-07 11 2004 2 BEDT2
0 0 15-21 10 2005 0 BEDT2
0 0 01-07 11 2006 0 BEDT2
0 0 08-14 10 2007 0 BEDT2
0 0 08-14 10 2008 0 BEDT2
0 0 15-21 02 2003 0 BEST3
0 0 15-21 02 2004 0 BEST3
0 0 15-21 02 2005 0 BEST3
0 0 15-21 02 2006 0 BEST3
0 0 22-28 02 2007 0 BEST3
0 0 15-21 02 2008 0 BEST3

Note: Date ranges must be exactly 7 days.
I guessed the starting date for 2008.
