DateTime epoch conversion

Forums
Gurux.DLMS

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);

problem with date and time in ION

Forums
Gurux.DLMS

Greetings,

When I query the time and date of the meter using GXDLMSClock() everything works as expected, since this meter is parameterized with UTC time -5 it is used:
client.useUtc2NormalTime = True
System Time: 09/22/23 15:00:31
Meter Time: 09/22/23 15:00:30
It works perfect.

but when I read the load profile the data comes with -1 day
