SB 5.24.11

yatra ha vāva na bhayam aho-rātrādibhiḥ kāla-vibhāgair upalakṣyate.
Word for word: 
yatra — where; ha vāva — certainly; na — not; bhayam — fearfulness; ahaḥ-rātra-ādibhiḥ — because of days and nights; kāla-vibhāgaiḥ — the divisions of time; upalakṣyate — is experienced.
Translation: 
Since there is no sunshine in those subterranean planets, time is not divided into days and nights, and consequently fear produced by time does not exist.
