Srimad Bhagavatam Canto 10, Chapter 14, Text 43

SB 10.14.43

ekasminn api yate ’bde
pranesam cantaratmanah
krsna-mayahata rajan
ksanardham menire ’rbhakah
 
Translation: 
 
O King, although the boys had passed an entire year apart from the Lord of their very lives, they had been covered by Lord Krsna’s illusory potency and thus considered that year merely half a moment.
