RE: Bug report for "date"

[Paul Grinberg]

Phil,

 As I said...it is a workaround, since ins Solaris you cannot execute
that command:

# date -R --date="-14 days"
date: illegal option -- R
date: illegal option -- date=-14 days
usage:  date [-u] mmddHHMM[[cc]yy][.SS]
        date [-u] [+format]
        date -a [-]sss[.fff]


Best,
Paul

That script is using (/abusing) TZ beyond its stated purpose. As Bob 
suggests, GNU date can perform date calculations with relative offsets, 
e.g.

$ date -d 'now + 12 days'
