Converting to unix time worked for me;

... | eval AAA = (your_time_field - 25569) * 86400 | convert ctime(AAA)

where 25569 is the actual number of days between Jan 1 1900, and Jan 1 1970 (according to some online calendar tool - din't count them myself).

Subtract, multiply, convert, ACTION.

I would like to do it at index time but doing it at search would be acceptable.

Where are you trying to do the conversion? In a search, or at index time?
