You can always refer man pages for options. Like as follows.

As above quotes, you can take one example who -b tells same like when a person(OS this case) born(came up) and uptime tells how old a person(OS this case, means what time it got rebooted last time) is. Just an silly and simple examples. Hope this helps you.

That doesn't answer the question. On my system, the command line:
produced the output:
a few minutes ago. That shows a boot time reported by uptime about two minutes later than the time reported by who -b. I can blame that on the times being recorded at different phases in the boot process. I think seenuvasan1985 is asking why the timestamps on his system are ~6 months apart. Why did his system go down and come back up without rebooting?
Maybe someone took the system down to single user mode and then brought it back up to multi-user mode 187 days ago without rebooting???
I'm trying to get the uptime of my computer (Mac OS X) and I can go into the terminal and type "uptime" OK, and that gives me a string with the uptime in it. The problem is that the string changes a lot, and its very difficult to get the data I'm trying to extract out cleanly.

On HP-UX, the 13th argument of uptime is sometime the load and sometime the word AVERAGE:???

My Linux system was last rebooted few hours ago.
But it seems little confusing for me to figure out the exact reason behind it.
I guess following command should justify what i meant to say.

I want to extract the uptime from the output of the uptime command.
The output:

uptime
UPTIME(1) User Commands UPTIME(1)NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime [options]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
OPTIONS -p, --pretty
show uptime in pretty format
-h, --help
display this help text
-s, --since
system up since, in yyyy-mm-dd HH:MM:SS format
-V, --version
