Hi,
If you want to keep you date time in UTC format, in your microflows you need to operate on that attribute using function call with UTC. For example parseDateTimeUTC(xxxxx, xxxx), if you will use that function, then date and time will be taken from UTC Time (2022-01-19 00:00:00.00).
If you will use simple parseDateTime it will be converted to session time of user, that executed this microflow – in your case – 2022-01-18 20:00:00.000 -0400.
Same with other functions formatDateTime, formatDate…
