Time lib error on code that compiled before?

Projects Programming
1

Hi, I built a device to pressure test equipment to see if it will leak underwater and it has work great but now i am building a few more and my same code will not compile due to an error in the Time Lib.
Anyone out there familiar with the time lib and can help?

this is the error message i am getting when i try and compile.
Compiling sketch...

Unless you post the sketch, it will be hard to find the problem. Please don't forget to use code tags when you do that.

Hi,
This forum is a community.
Those who help on this forum are volunteers and receive nothing but criticism or praise.
(or get paid if posted in the "Jobs and Paid Consultancy" category).
They often receive a lot of joy knowing that we were able to help someone, and this one expresses a lot of joy in accomplishing what alone I was not able to.

We are very happy to help you with your idea or difficulty.
But to facilitate our understanding of it, we give here a suggestion of how
you must expose:

Simply and clearly describe the idea or difficulty you are having, and
provide additional information such as:
post (using the appropriate tags </>) the sketches you are using in the project, and
make sure it is commented out and formatted;
post (using the appropriate tags </>) error printouts;
the ucontroller used in the project; ,
the schematic of the connections of the components involved in the project;
libraries link let us know how it is and which version;
drawings, photos, etc.
(Sorry for language errors, English is not my native language).

I think this is a clue. Possibly, one of the other libraries you included is using a different Time library, and it's causing the conflict.

I really don't believe there is anything "wrong" with any of the Time libraries... it must be how you are using them, or how you installed them.

I use the DateTime library, I believe it supercedes the others, except on platforms that have a fully implemented Time library natively, such as ESP. If I'm programming on ESP, I use that, not any external library such as made for AVR-GCC because of how they truncated the native version.

You could temporarely make "Time-master" library disappear (move it to a usb key or something) and see if your sketch compiles.

pretty much anytime there is a library in a directory named
xxx-master like in your case Time-master
it indicates a library was installed from a zip file from github and it was installed incorrectly.

If you use the zip install function from the IDE library manager on a zip file from github the library will be installed incorrectly and can cause problems due to the potential of installing duplicate libraries with the same name especially when mixing multiple libraries or using zip install and the library manager download capabilities.
This is an issue caused the by github creating their zip files in a goofy format that includes the branch name as the name of the root directory.
The IDE could work around this but it doesn't

Also, while this "Time" / "TimeLib" library is available in the IDE library manager for downloading its name can cause issues on Windows machines.
The original name was "Time" and sketches used the header file <Time.h>
The problem is that Windows does not handle case sensitive file names.
As a result if you include <Time.h> that is the same as <time.h> and on newer platforms <time.h> is now part of the system cross compilation tools.
So on Windows things got confused.
The solution was to add a file named TimeLib.h so the user would include <TimeLib.h> and avoid the Time.h vs time.h issue.
This is a hack and was not a proper solution, the reason being that the directory for the "Time" library is still called Time even though sketches are now including <TimeLib.h>
While this can work, it is still subject to potential issues.
The IDE gives preferential treatment when the directory name of a library matches the header file basename i.e. TimeLib directory for a header named TimeLib.h
What should have happened is that the library name in the IDE library manager should have been changed to TimeLib so that it matches the header file basename for the main header TimeLib.h

The safest way to ensure that there are no issues, particularly on Windows machines, is to install the library using the IDE library manager which will put the library in a directory named Time
Then go manually rename that directory TimeLib
And in the sketch always include <TimeLib.h>

I'm guessing that if you were to remove your two Time libraries that are installed on your system and re-install it from the IDE library manager (NOT using a zip file) but let the IDE download and install it, and then after it is installed in the Time directory renaming the Time directory to TimeLib
Things will work again.
