In my app I'm reading some data from excel sheet and i stucked in the moment when i want to get timestamp from a cell. In this speciffic cell i got a value '1900-01-02 13:20:04' and in excel i am using format '[h]:mm:ss' which formats this value to '61:20:04', which is correct beacuse those cells are showing hours worked by some employees.
What I want to achieve is to read this data from excel in the same format as it's formated in excel('61:20:04') and save it to string. My problem is how to read this, or convert to this timestamp value ?

EDIT.(the way i am doing it now)

I am reading the code from excel using ODBC so just select data i need(like sQl select) -> add all data to datatable and then i'm just doing 

dr["workedHours"].ToString() -(dr = DataRow in my DataTable.Rows) this line returns '1900-01-02 13:20:04'. How can I convert it to time like excel does.
