You can nail this with reactive extensions which will take care of lots of timer related problems for you (clock changes, app hibernation etc). Use Nuget package Rx-Main and code like this:

Action work = () => Console.WriteLine(DateTime.Now.ToLongTimeString());

Scheduler.Default.Schedule(
    // start in so many seconds
    TimeSpan.FromSeconds(60 - DateTime.Now.Second), 
    // then run every minute
    () => Scheduler.Default.SchedulePeriodic(TimeSpan.FromMinutes(1), work));               

Console.WriteLine("Press return.");
Console.ReadLine();
