[INDOLOGY] Gayatri mantras to time

[Harry Spier]

Dear list members,

1) I was asked to find any gayatri mantras to time or that mention
time. Does anyone know of any or have ideas about where to look.  I've
looked in GRETIL and the Muktbodha searchable library but didn't find
any.

)In the following Gayatri mantra from the internet
https://www.youtube.com/watch?v=QCIGR0cpiyc

 oṁ kāla-kālāya vidmahe
kālātītāya dhīmahi
tan no kāla-bhairavaḥ pracodayāt

How would you translate kāla-kāla in the first line. Someone suggested
"death of time".  Is that a possible translation.

Thanks,
Harry Spier
