how to set epoch value to

[reney44]

i find epoch time from my token $date1$ using below code
index="cdq-dashboard-dev"|eval earliest="$date1$"| convert timeformat="%Y-%m-%d" mktime("earliest")|convert num("earliest")|eval latest=earliest+86400|convert num("latest")|eval earliest-time=tostring(earliest)|eval latest-time=tostring(latest)|dedup earliest-time |table earliest,latest,latest-time,earliest-time

then get the epoch vale in string as well as number.
i want to filter using epoch value like below but its not working
$epoch_earliest$
$epoch_latest$
but its not working

This is a mess; you are doing WAY too much work. Try using fieldformat which causes the value to present to you formatted but retains the unformatted value underneath (so that you can do math and comparisons):

index="cdq-dashboard-dev"|eval earliest="$date1$"
| bin earliest span=1d
| dedup earliest 
| eval latest = earliest + 86400
| fieldformat  earliest = strftime(earliest, "%Y-%m-%d")
| fieldformat  latest = strftime(latest, "%Y-%m-%d")
| table earliest latest
