Symptoms
Dates from K2 are off since either the 4.6.9 update or daylight savings
Diagnoses
I've noticed that the dates being push into SQL are off by one day since either the 4.6.9 update or daylight savings. When I run execute smart objects they now show yesterday on my date fields. Multiple projects which I haven't changed
Resolution
K2 introduced a new data type with 4.6.9. of Date and Date/Time when working with SmartObjects. The Type needs to be adjusted on the smartobject to reflect the type of information your saving (i.e. with or without time). The customer changed the SQL column type from Date to Date/Time and rebuilt the smartobject to reflect those changes. It is now putting in the correct date for the time zone.
