You can control this behavior by calling one of the overloads of that includes a parameter. find a partner nz. The result string produced by many of the custom date and time format specifiers also depends on properties of the current DateTimeFormatInfo object. Time zones are interpreted as text if they have names. The following example is like the previous one, except that "pst" is enclosed in quotation marks to indicate that the entire delimited string should be interpreted as character literals. The second parameter of the method is tagged with the ParamArrayAttribute attribute, which allows you to include either a delimited list or an object array as your format list.
