Is there any way to know when I flashed my last custom ROM?

Atleast a smart way to find the approximate date/time using some logs deep down in my android would be good.

Try the following in Terminal Emulator or ADB shell:

ls -l /system/

The date stamps on the read-only files/directories are the time they were created, i.e. approximately when the ROM was installed.

Great answer. There's no need to issue the cmd "su". I issued only the second line without root access and it worked great. – Nadav S. Jun 28 '14 at 16:58
