Kibana epoch time in data links

Hello all,

Related to https://github.com/grafana/grafana/issues/1909, I misunderstand something
I found no way in Data links to pass __from and __to in kibana format

Or better with something like ( __from - 5M) and (__to + 5M)

How do you manage the data links with kibana ?
My goal is very simple when an alert is generate I need a link to kibana with the good query (and I have many, A,B,C,D,E, etc) and the good time range or at least something close

Thank you
