What if I should fall between the cracks?

 Will I go back and forth down on-line?
 Wherever!  It's a question of time

 Watching my sand glass
 I count to a thousand
 I flip it over
 A lifetime in my hand

 I set the counter
 And switch on the power
 Transform my matter
 Am I gone forever?

 Am I tomorrow or yesterday?
 Another second's just passed away
 Upcoming present and future past
 Am I the first?  Could be the last

 Over and under
 I spiral down the line
 I'm getting closer
 I must be right on time
 Closer, closer
