Datetime field issue

[Vishwa_Kumar]

I have a custom datetime field, it appears that when I send the data this is being adjusted, e.g.

if datetime is sent as 2020-01-06 06:12:10.107,

the transferred data in Marketo shows 01/05/2020 4:00 PM

Is this a time zone adjustment or something else, how to see the correct date and time data as it is passed ?

Send the data as UTC (Z), otherwise, by the definition of ISO 8601 timezones, it's in local time.
