date: illegal option -- d in sun solaris

Hi all,

I am trying to execute the following command in a sun solaris machine and getting the error as below.

Code:
bash-2.03$ date -d "1 day ago" +%Y%m%d
date: illegal option -- d

bash-2.03$ uname -a
SunOS gtrd02 5.8 Generic_117350-55 sun4u sparc SUNW,Sun-Fire-V440

Can anybody help me to find an alternate way to calculate yesterday's date with out using the -d option?

Code:
YESTERDAY=`TZ=GMT+24 date +%d-%m-%Y`; echo $YESTERDAY

NAME
APR::Date - Perl API for APR date manipulating functions Synopsis use APR::Date (); # parse HTTP-complient date string $date_string = 'Sun, 06 Nov 1994 08:49:37 GMT'; $date_parsed = APR::Date::parse_http($date_string); # parse RFC822-complient date string $date_string = 'Sun, 6 Nov 94 8:49:37 GMT'; $date_parsed = APR::Date::parse_rfc($date_string); Description "APR::Socket" provides the Perl interface to APR date manipulating functions. API
"APR::Date" provides the following functions and/or methods: "parse_http" Parse HTTP date strings $date_parsed = parse_http($date_string); arg1: $date_string ( string ) The date string can be in one of the following formats: Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format refer to RFC2616 for the details (GMT is assumed, regardless of the used timezone). ret: $date_parsed ( number ) the number of microseconds since 1 Jan 1970 GMT, or 0 if out of range or if the date is invalid. since: 2.0.00 Remember to divide the return value by 1_000_000 if you need it in seconds. "parse_rfc" Parse a string resembling an RFC 822 date. It's meant to be lenient in its parsing of dates. Hence, this will parse a wider range of dates than "parse_http()". $date_parsed = parse_rfc($date_string); arg1: $date_string ( string ) The date string can be in one of the following formats: Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format Sun, 6 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sun, 06 Nov 94 08:49:37 GMT ; RFC 822 Sun, 6 Nov 94 08:49:37 GMT ; RFC 822 Sun, 06 Nov 94 08:49 GMT ; Unknown [drtr@ast.cam.ac.uk] Sun, 6 Nov 94 08:49 GMT ; Unknown [drtr@ast.cam.ac.uk] Sun, 06 Nov 94 8:49:37 GMT ; Unknown [Elm 70.85] Sun, 6 Nov 94 8:49:37 GMT ; Unknown [Elm 70.85] ret: $date_parsed ( number ) the number of microseconds since 1 Jan 1970 GMT, or 0 if out of range or if the date is invalid. since: 2.0.00 Remember to divide the return value by 1_000_000 if you need it in seconds.
