Epoch dates for the start and end of the year/month/day Convert seconds to days, hours and minutes What is epoch time? The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking the epoch is Unix time 0 (midnight 1-1-1970), but 'epoch' is often used as a synonym for 'Unix time'. Many Unix systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038).

FIND OPEN TCP PORTS AND PIDs
PCP script to find open TCP ports and PIDs in Solaris
PCP is a script that can help you quickly find Processes (PIDs)
having particular TCP Port(s) open, TCP ports open by specific PIDs
or even list all the TCP Ports open by all PIDs running on your system.
PIDs for TCP Port
Run PCP with "-p" option to show the PIDs of processes having a
TCP port (say Port 22)
Example:
test@mx3 # ksh "pcp.ksh" -p 22
PID Process Name and Port
_________________________________________________________
26308 sshd 22
sockname: AF_INET 10.0.0.7 port: 22
sockname: AF_INET 10.0.0.7 port: 22
sockname: AF_INET 10.0.0.7 port: 22

TCP Ports open by PIDs
Run PCP with "-P" option to show the TCP ports open by specific PID
PIDs for all open TCP Ports
Use the "-a" option to list all TCP ports open with all the PIDs
