DateTime epoch conversion

Hi Mikko,

We have extracted the block load profile data and acquired the accurate date and time for 15-minute block intervals in GXDLMDirector. For example:

26/09/2023 00:15:00
26/09/2023 00:30:00

However, when utilizing the ToUnixTime function from the GXDateTime object to convert time to epoch and back to regular time, we are encountering the following discrepancies:

DateTime dateTime = new DateTime(1970, 1, 1, 0, 0, 1, DateTimeKind.Utc);
return Convert.ToInt64((date.ToUniversalTime() - dateTime).TotalSeconds);

26/09/2023 00:14:59
26/09/2023 00:29:59

Could you kindly provide your recommendations on how we can obtain the correct datetime from epoch in DLMS? and which one is correct ?

Hi,

The correct EPOC time is this.

DateTime dateTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

You need to change seconds from 1 to zero.

Mikko
