Posted 2021-05-07

# Working
docker run -ti php:7.1.7-fpm-alpine php -r "var_dump(strftime('%c', time()));"
#=> string(24) "Mon Jul 24 18:09:54 2017"

# Also working
docker run -ti php:7.1.7-fpm-alpine php -r "var_dump(strftime('%I:%M%p', time()));"
#=> string(7) "06:12PM"

# Not working
docker run -ti php:7.1.7-fpm-alpine php -r "var_dump(strftime('%I:%M%P', time()));"
#=> bool(false)
