If NLS is enabled, the result of this function depends on the current locale setting of the Ctype convention. Input: time stamp (timestamp), timestamp_base_string (string) Output: seconds (dfloat) Examples. This is because the transformer compiler does not convert the function result for these functions to a string. The only exceptions are the functions StringToUstring and UstringToString (). The LEN function includes all blank spaces, including trailing blanks, in the calculation. Any other value causes a runtime warning, and 0 is returned. 2 conversion is invalid.
