I want to add 2 days to it and change time to 13:00
[OutDateTime] = 2022-03-23 13:00
You can use DateTimeTrim expression to cutoff the hours and use the DateTimeAdd expression to add 61(24*2+13) hours.
DateTimeAdd(DateTimeTrim([datetime],"day"),61,"hour")

Since " 2022-03-21 10:00" is not a standard Date Time format, I am afraid we need to some parsing first.
