Type validation is already being handled in the cron:runAt event. Please remove the redundant code.

Refactor to call os.date("*t", timestamp) once, store the result in a local table, and extract the required fields (day, month, year) from that table. This improves efficiency by avoiding repeated parsing and enhances code readability and maintainability.

for i = 1, #cronJobs, 1 do
local scheduledTimestamp = os.time({
hour = cronJobs[i].h,
min = cronJobs[i].m,
sec = 0, -- Assuming tasks run at the start of the minute
day = os.date("%d", timestamp),
month = os.date("%m", timestamp),
year = os.date("%Y", timestamp),
day = currentDay,
month = currentMonth,
year = currentYear
})

if timestamp >= scheduledTimestamp and (not lastTimestamp or lastTimestamp < scheduledTimestamp) then
