I have often run into the need to convert a large list of timestamps from Unix Timestamp to a readable date.
Often times this is simply a need that I have when receiving an error message from a server, or when reviewing log files which only use Unix Timestamps.
So I created a simple utility, just paste in your text from the log file, the utility will search out the string for timestamps listed as the first part of each line, and convert the timestamp to a date.
While this might be useful at some point as an automated process, for now I just use it when I need it.
I am documenting the tool here with a link for myself (or any one else that may need it) so that it is simple to find.
Possible future upgrades to this utility will likely search out Unix Timestamps anywhere in the text and convert them, instead of just at the first of the line.
