the desire is to obtain IDs of triggers that have fired in a given timeframe.

trigger.get method has two parameters to limit by the time when triggers have fired :

• lastChangeSince
• lastChangeTill

unfortunately, the lastChangeTill does exactly what the name implies - limits triggers to ones that had their last change until the specified time.

let's say it's 2016-09-14 now, and we would like to get all triggers that fired in february this year.
we can set lastChangeSince to 00:00:00 feb 1st.
unfortunately, setting lastChangeTill to 00:00:00 mar 1st will exclude all triggers that fired in march and later.

it might be useful to have a parameter like hasChangeTill, that would return "anything that fired until that time, no matter whether it fired afterwards or not".

if there is a way to get such data, sorry for missing that in the manual and i'd appreciate any pointers
