I'm working on a project. The idea is that it has two input files, we'll call them TimeFile and FullFile.
TimeFile gives two timestamps in the format:
DD-MM-YY HH:MM:SS DD-MM-YY HH:MM:SS
And FullFile is in the format of a timestamp and some data:
YYYY-MM-DD HH:MM:SS Value Error Error
The idea is that the program reads the timestamps from TimeFile, then goes through all the lines in FullFile, and if it finds a timestamp from FullFile that lands between two from TimeFile, it copies the whole line into a new smaller data file. In essence, I want to go from one gigantic data file to a bunch of smaller data files divided up by time intervals.
Needless to say, it doesn't work. It does most of what I want, but the resulting smaller data files are always empty.
The strange part is why. It appears to read the timestamps from TimeFile just fine, but it screws up reading from FullFile and just reads the first line over and over again. I don't really have a solid idea why either, best I can determine is that they're reading the same way, but one works and the other doesn't.

I'm stumped, any help would be appreciated.
Edit: Thinking it might help if I give a few lines of each of my data files to see if it's a formatting issue, so here's the first 3 lines of each:
TimeFile
03-Apr-22 22:42:19 03-Apr-22 22:56:13
03-Apr-22 22:58:25 03-Apr-22 23:15:14
03-Apr-22 23:17:23 03-Apr-22 23:35:32
FullFile
2022-04-13 12:39:37.500000000 70.00000 0.0 0.0
2022-04-13 12:43:52.500000000 70.00000 0.0 0.0
2022-04-13 12:48:07.500000000 70.00000 0.0 0.0
Edit2:- Important discovery. Running this code with that block uncommented out reproduces the data in the line but instead of 70 0 0 you get 1 0 43.1495 for the last three values. GetLine doesn't seem to do this but I'm having trouble understanding how to cut that open.
Not entirely sure what this means beyond that somehow that's not reading those values properly but when I try to account for a tab it's not an improvement.
