How can I set "_time" = "initialQueryTime" in the summary index?

[lpolo]

I need to set the "_time" of a summary index equal to the time of a field value.
Like for example:
Event:


abc

In this particular example I need to set "_time" = "initialQueryTime" in the summary index.
I tried using in my schedule search the following eval:
eval _time=relative_time(initialQueryTime, "0d@d") but it does not work.

I am able to get the date but not the time of the date like this:
eval _time=relative_time(now(), "-23d@d")

How can I set "_time" = "initialQueryTime" in the summary index?

Any idea.....

Thanks for your help....

I could not find a solution. So I used "eval _time=relative_time(initialQueryTime, "0d@d")"
