Details:
Two examples of valid syntax for date follows:
date -d "12:00 1 year ago"
date -d "12:00 a year ago"
The 'date' command acts as if it understands the indefinite article 'a' in
this case. However, the time returned is off by one hour.
Sample output:
bash-3.00$ date --version | head -1
date (GNU sh-utils) 2.0
bash-3.00$ TZ=UTC
bash-3.00$ date -d "12:00 1 year ago"
Tue Mar 29 12:00:00 UTC 2005
bash-3.00$ date -d "12:00 a year ago"
Tue Mar 29 13:00:00 UTC 2005
bash-3.00$ date -d "12:00 a month ago"
Wed Mar 1 13:00:00 UTC 2006
bash-3.00$ date -d "12:00 next month"
Sat Apr 29 12:00:00 UTC 2006
bash-3.00$ date -d "12:00 a month ago next month" # today
Wed Mar 29 13:00:00 UTC 2006
