Question Yesterday in UNIX

Hi,
I want to set a cron job with the yesterday date in a unix server (solaris).
  • I tried TZ=CST+24 date +%Y%m%d but i had TZ=CST+24: not found
  • I tried `perl -mPOSIX -e 'print POSIX::strftime("%Y%m%d",localtime(time() - 86400)) '` it works but I'm not sure that all the clients have perl in their machines.
  • date -v and date -d don't work only -u and -a options work with date in unix:
    date: illegal option -- d
    usage: date [-u] mmddHHMM[[cc]yy][.SS]
    date [-u] [+format]
    date -a [-]sss[.fff]

Anyone has an idea please.
Thanks

NAME
pmdate - display an offset date SYNOPSIS
pmdate [ offset ... ] format DESCRIPTION

An offset is specified with a leading sign (``+'' or ``-''), followed by an integer value, followed by one of the following ``scale'' spec- ifiers; S seconds M minutes H hours d days m months y years The output format follows the same rules as for date(1) and strftime(3). For example, the following will display the date a week ago as DDMMYYYY; pmdate -7d %d%m%Y PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura- tion file, as described in pcp.conf(5). SEE ALSO
