Date difference in Interface Vs Process model

Question

Hello All, 
 
 I have an interface, where I am using a!dateField() component to select the date ranges. 
 If I select 18th Sep in the interface and submit the form, Its getting stored as 17th Sep in the process variables. And I am storing the same PV value into SQL Sever its storing as 18th Sep which is correct but when I retrieve it back again its returning 17th Sep. 
 Can you please help me finding why there is 1 Day difference between interface and the process variables? 
 
 Note: When I test the interface rule its storing proper value in the Rule input Variables. 
 
 Kind Regards!!

Hi sujithap, 
 
Date component behaviour in ProcessModel: 
Time zone context used by the process. This value may differ from the configured process model time zone, such as when the designer selects the option to override the configured process model time zone with the process initiator's time zone. 
 
Interface: 
When Datetime values are presented to users in the interface, they are always adjusted to the current user's time zone. This may cause the expected output to vary significantly. Additionally, the acronym of the user's local time zone (such as EDT) is appended to a displayed Datetime value when it appears in a form, an alert, or in an email.
