The 'TZ' parameter permits overriding the default time zone. 'CST' is the name of a timezone.

I have a Q. what is the difference between CST & PST?

TZ=CST+24 date %d
TZ=PST+24 date %d

if I want to get the "day" of a date, instead of using `datecalc -D {date}`, any other options?

Code:
perl -e '@arr=localtime(time() - 86400); print @arr[3]'
