Sorry, it is probably not Spain, I Googled too quickly. I'll stop making wild guesses. :-)
The OP's IP is reported as 201.235.35.174, which looks like Buenos Aires, Argentina, so UTC/GMT -3 hours perhaps.
That's a better guess. Making wild guesses quickly without engaging the brain was dumb. :-) Here is a simple implementation for Diego, perhaps it's closer to his requirements. It can be shorter, but is laid out for clarity. Only does local time, however. 
-- start_date: day on which campaign starts (table)
-- end_date: day on which campaign ends (table)
-- (inclusive, assume the whole of end_date
-- is still a campaign day)
--
-- start_time: time on which campaign starts (table)
-- end_time: time on which campaign ends (table)
-- (exclusive, last valid time is 1 second
-- before end_time)
--
-- * Assume for dates, year,month,day are valid
-- * Assume for times, hour,min are valid
--
-- (1) test if current date is in campaign date range
-- and if true, then,
-- (2) test if current time is in campaign time range
-- and if true,then,
-- (3) run something
-- current date/time
local today = os.date("*t")
local t_today = os.time()
-- DEBUG some values for testing only
local start_date, end_date = today, today
local start_time = {hour=17,min=0}
local end_time = {hour=19,min=0}
-- dates to compare (time made up as date at midnight)
local d_start =
 os.time{year = start_date.year,
 month = start_date.month,
 day = start_date.day,
 hour = 0, min = 0}
local d_end =
 os.time{year = end_date.year,
 month = end_date.month,
 day = end_date.day,
 hour = 0, min = 0}
local d_today =
 os.time{year = today.year,
 month = today.month,
 day = today.day,
 hour = 0, min = 0}
-- check if today is a campaign date
if d_today >= d_start and d_today <= d_end then
 local t_start =
 os.time{year = today.year,
 month = today.month,
 day = today.day,
 hour = start_time.hour,
 min = start_time.min}
 local t_end =
 os.time{year = today.year,
 month = today.month,
 day = today.day,
 hour = end_time.hour,
 min = end_time.min}
 -- check if now is within campaign time
 if t_today >= t_start and t_today < t_end then
 print("Yep")
 else
 print("Nope")
 end
end
Something like that.
