function Time = importTime(filename, dataLines)
%IMPORTFILE Import data from a text file
%  Time = IMPORTFILE(FILENAME) reads data from text file FILENAME
%  for the default selection.  Returns the numeric data.
%
%  Time = IMPORTFILE(FILE, DATALINES) reads data for the
%  specified row interval(s) of text file FILENAME. Specify DATALINES as
%  a positive scalar integer or a N-by-2 array of positive scalar
%  integers for dis-contiguous row intervals.
%
%  Example:
%  Time = importfile("C:\Users\menzifr\Documents\3_My_SW\LEO_SPS\GINav-main(1)\GINav-main\data\LOWLEO_new\sat_data_V1A1.csv", [2, 2]);
