January 19, 2038, is a significant date known as the "2038 problem" or the "Unix Y2K." It is related to the representation of time in many computer systems that use a signed 32-bit integer to store the time in seconds since January 1, 1970, at 00:00:00 UTC (known as the Unix e...
Could anyone show me how I could obtain the current UNIX epoch time in milliseconds? I've tried using the method below, but this seems to return the current epoch time in seconds bash-3.00$ perl -e 'print time,"\n";' 1144577446 ...

Unix Epoch time is always UTC +0, and when you load this report in the service, DateTime.LocalNow() as I used above also calculate as UTC +0, so it will be apples to apples. Once you get it into Unix Epoch time, then add (3600 * n) seconds to your final answer, where N is...
