Operating Environment: Linux (3.13.0-62-generic, amd64) / UTF-8 / en / IN / Oracle Corporation 1.8.0_40-b26

Steps to reproduce the issue :
1) Connect to Sybase Anywhere 16 Database.
2) Create a Table with time data type in any schema.

CREATE TABLE nishtha.test_time  (
    c1    time NULL
    )
GO

3) INSERT some values in this table.

INSERT INTO nishtha.test_time(c1)
    VALUES('18:15:30')
GO

4) Run Select * query to check data.
SELECT * FROM nishtha.test_time
GO

5) Now Export data of this table into test_time.csv file.

Data in "test_time.csv" file :

5) Also Export data of this table into test_time.xls file.

Data in "test_time.xls" file is :

Data is exported as String.

7) Now Import data from "test_time.csv" file into table 'test_time'.
    Data imported successfully.

8) Now Import data from "test_time.xls" file into table 'test_time'.
    Below error message is displayed.
    test_time --> Warning: Row: 1 -- Column:c1 type:time :Unparseable date: "0001-01-01 18:15:30.0" --

Time value is exported as String And when we import this value in to table 'test_time', error message is displayed and Null is inserted into table.

Is this acceptable?

Please refer attached screenshot "SybaseAnywhere_time_datatype.png".
Also refer attached "test_time.csv" and "test_time.xls" files.

Observation : In PostgreSQL and Sybase ASE databases if we export value of time datatype into excel file, data displayed in excel file is :

Value is exported as Date into excel file.

And when we Import this value into table, data imported successfully.
