Cannot use GetDate by PHV on AIX

[needcoffee]

I cannot determine why this script How do I get any date relative to today (in ksh) by PHV to work on AIX. I think it may be how 5.2 returns $TZ but I am lost on how to debug this. Can someone lend some expertise?

Here is $TZ in ksh on my machine:
EST5EDT,M3.2.0/2:00:00,M11.1.0/2:00:00

Thanks in Advance,

Did you read PHV's note?

#-- Note:
On some *nix flavor the authorized displacement is limited to +/-168 hours and thus the above "Next week" test fails.

I think AIX is one of those "limited" *nixes.

p5wizard,

The max change I am using this for is 6 days so I am below this threshold. Do you have any suggestions on an alternative way to do this?

Thanks,

I've used a similar function on AIX to get yesterday's (or tomorrow's ?) date on AIX, but I'm not at a machine right now. I'll see if I can dig it up tomorrow.

Take a look at William Robert's shift_date script:

PHV's code looks OK to me...

[tt]$ cat getd
GetDate(){ # GetDate nDays [format]
typeset -i nDays=$1; format=$2
eval $(echo $TZ | sed '
s!\([^-0-9]*\)\([-0-9]*\)\(.*\)!typeset -i localOffset=\2;zon1=\1;zon2=\3!')
TZ=$zon1$((localOffset-24*nDays))$zon2 date $format
}

echo "Yesterday: $(GetDate -1)"
echo "Tomorrow: $(GetDate 1)"
echo "Next week: $(GetDate 7 '+%Y-%m-%d')"
$ # on my timezone:
$ echo $TZ
CET-1CDT,M3.5.0/02:00,M10.5.0/03:00
$ ./getd
Yesterday: Wed Apr 16 08:51:26 CDT 2008
Tomorrow: Fri Apr 18 08:51:26 CDT 2008
Next week: 2008-04-24
$ # on yours:
$ TZ=EST5EDT,M3.2.0/2:00:00,M11.1.0/2:00:00
$ ./getd
Yesterday: Wed Apr 16 02:51:33 EDT 2008
Tomorrow: Fri Apr 18 02:51:33 EDT 2008
Next week: 2008-04-24[/tt]

OK,

Got it working. I am officially a moron this week due to sleep deprivation. I forgot to call the funtion again within the script I put this into.

My apologies all,
