Question

In TeamCity is there an easy way to get a variable for the current date in the format MMdd (eg 0811 for 8-Aug)?

Answer 1

For Unix based build agents I propose next custom script as one of build commands:

export current_build_date_format="+%%Y.%%m.%%d"
export current_build_date="$(date $current_build_date_format)"
echo "##teamcity[setParameter name='env.current_build_date' value='$current_build_date']"

You have to make double % sign to avoid interpretation for date executable command line argument FORMAT string (see %Y.%m.%d) as already existing TeamCity variable.
