# date command is all we need, as shown:
#date -d '2007-011-01 17:30:24' '+%s'

#date -d '2007-011-01 17:30:24' '+%w'

# Usage:
# Call this script and generate a new testUnixtime.lua
# Run the test afterwards like the following:
# $ lua testUnixtime.lua
# remove the tailing "./" and the extension of this script
OUTPUT="$(echo "$0" | sed 's;^./;;' | cut -d'.' -f1).lua"
#rename OUTPUT from generate to test
OUTPUT="$(echo "$OUTPUT" | sed 's;generate;test;')"
