mysql - Looking up times in DB based off actual time or actual time including Delay -

i looking way able grab rows database time.

two columns exist: time - scheduled time delay - +seconds time delayed.

let's say:

id,time,delay 1,18:23,360 2,18:25,0 3,17:15,-60

now, let's searching buses after arriving at/after 18:25, how include these 2 results:

2,18:25,0 1,18:23,360 (note: 18:23 + 360 seconds  = 18:29)

in query like

where `time` >= '18:23'

thanks

select * [table] date_add(time,interval timedelay second) >= '18:25:00'
