If I call sys.epoch function on date beyond 19-01-2038 03:14:00, what I get back is a negative number. I understand that this is an overflow issue, but currently there is no work-around for this problem in monetdb.
Reproducible: Always
Steps to Reproduce:
select sys.epoch(str_to_timestamp('19-01-2038 03:15', '%d-%m-%Y %H:%M')) AS "timestamp";
Actual Results:
-2147483596
Expected Results:
2147483700
I am actually using sys.epoch to evaluate the mean (avg) over a date column: Is there an alternative workaround for that ?.

given the current data type (int) used an error should be given by the epoch function. Somehow we need to switch to BIGINT.

(In reply to Niels Nes from comment 1)
Would it be possible to introduce a new function returning a bigint ?
