As I walked vs Ponder

 In Auden's poem the poem is essentially about how 'Time' will eventually 'conquer' us all and the naive lover introduced in stanza 2 is warned by a personified Time that the promises. The lover’s song promises unending love and devotion as the lover says his love will last until impossible things occur such as the ocean drying up and the stars "squawking like geese". While in Cummings poem the speaker is using time as a justification to seduce the woman into "horizontal business".
