Hello,

 

Don't do that. It will almost certainly introduce issues related to timezones and DST, which you'll hate fixing. Instead try to pass those timestamps in complete ISO format (with date, time and zone), and format as dates only when you present them to the end user, e.g. in a mashup or in a CSV file.

Hi @JY_11008628 ,

 

Can you please post the result of the same query executed by your DB's SQL manager ?

I am asking this because I would like to see with certainty that the SQL statement is correct (ThingWorx does not have a DATE basetype, as I presume you are already aware, but the SQL DATE I would expect to at least like 2025-09-04 12:00:00 etc)

    Choose your flavor. Mind the timezone.

     

    SELECT now() d1,date(now()) d2, now()::date d3, date_trunc('day', now()) d4, TO_CHAR(now(), 'DD/MM/YYYY') d5
