You've assigned to date-formatter-set-to-gmt-time the return value
from the setTimeZone method call. This method returns null, hence the
null pointer exception when you try to call the format method. 'doto'
might help here, like:
(let [gmt-date-formatter (doto (SimpleDateFormat. "yyyy-MMM-dd HH:mm:ss")
(.setTimeZone
(TimeZone/getTimeZone "GMT")))]
(.format gmt-date-formatter (Date.)))
