Currently, when we use time estimates in automation we need to check the work hours mentioned in the “Global Time tracking parameters" and then convert it into seconds and use it.
eg:
{[issue.timetracking.remainingEstimateSeconds.divide(288000}}
in the above example, we use 28,800 secs since the work hours per day is 8 (8*28800)

Now if we have multiple automation rules on the site and in case the work hours per day change to 7 or 6 in future, users will have to go make changes to all my automation rule and add the value (7*3600 or 6*3600).

It would be helpful to have a smart value that picks the Working hours per day from the Global time tracking.
