Question: I have a received a server log which has entries for each row with date something like this below. 

23:18.6

23:23.6

I want to convert these dates in DD/MM/YY HH:MM:SS format in excel, but when I do this I get value like 00/01/1900 00:23:19 

Please can you some let me know what kind of format is this date/time entries.

Answer: 
I used a simple approach to make this work:

1. Create Firebase database
2. Add your latest version
3. If the version is different than the installed version, show the popup of installing the update. It works perfectly for me...
You can notify your users that there is a new version of the current app available to update. Also, if this condition is true, you can block login in the app.

Please see if [this](https://github.com/jrvansuita/CheckNewAppVersionAvailable) provides you the solution.
