scheduledexecutorservice - JAVA - Executor Schedule get Time until next run -

currently using scheduledexecutorservice task every 45 minutes (for infinity).

 executor.scheduleatfixedrate(new runnable() {             public void run() {                ...  }, 10, 45 * 60, timeunit.seconds); 

i wondering if there proper way know how long until next iteration of executor?

my un-proper way add timer , resetting every iterator of executor feels bad.
