Converting CSV decimal time value in SQL select statement

I have a CSV file I'm loading into a dataset. The time field is actually a decimal value since the type is set to General. How can I convert this time (not Date) to hh:mm format in the SQL statement. I'm using C# to create the dataset. I'm guessing I need to cast but can't seem to find a solution.

Time        pH
0.000115741 7.4
0.0105208   7.6
0.0209375   7.9
0.0313657   7.7
0.0417824   7.6
