When using K2 across multiple time zones, it is important to understand how K2 converts date and time values from a client browser to the K2 server, and from the K2 server back to a client browser.
The IIS server receives the UTC value and converts it to server's local date time. This value is sent on to the K2 server as a server local date time string using the Sortable ("s") format. The K2 server reads the value as a server local date time and passes it on to the SmartObject service. The SmartObject service defines how to send this on to the line of business (LOB) system.
The SmartObject service reads a date from the LOB system and converts it to a server local date time. This is sent through the SmartObject service as a server local string to the IIS server using the Sortable ("s") format.
The IIS server receives the server local string, converts it to a UTC string using the Universal Sortable ("u") format, and sends this to the browser. The browser (SmartForms runtime) loads the date object from the UTC string and displays the date in the browser's time zone.
