   string originalTime 
) 
public String TimeZoneOffset( 
   java.lang.String originalTime 
); 
public:

def TimeZoneOffset(self,originalTime):

Parameters

originalTime

The string containing the time in PDF time format

Return Value

The time offset formatted as a string in one of the following forms:

" (empty string) if the time did not contain time zone information
UTC if the time was UTC
