Shock!
I suppose I would be in SHOCK too if I went to pure Linux anything after over 30 years of UNIX.
For years there has been talk of "generic" *NIX - and for many commands, generic works. However, "distributions" of *NIX, including Linux (which is usually lowercase, not upper case) all have there differences.
The little I know of Linux makes me doubt that Linux volume management has not gotten farther than the "divvy/fdisk" like ways that were common +- 12 years ago.
But they are different from using smit (as admin interface) or the *vg, *lv, *fs commands to make, change, remove volume groups, logical partitions, and file systems on AIX. Basically, every *NIX has there own way of doing the administration - and the "rosetta stone" approach is probably an excellent start for you own cheat-sheet.

TIME(2) Linux Programmer's Manual TIME(2)
NAME
time - get time in seconds
SYNOPSIS
#include <time.h>
time_t time(time_t *t);
DESCRIPTION
time() returns the time as the number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).
If t is non-NULL, the return value is also stored in the memory pointed to by t.
RETURN VALUE
On success, the value of time in seconds since the Epoch is returned. On error, ((time_t) -1) is returned, and errno is set appropriately.
ERRORS
EFAULT t points outside your accessible address space.
CONFORMING TO
SVr4, 4.3BSD, C89, C99, POSIX.1-2001. POSIX does not specify any error conditions.
NOTES
POSIX.1 defines seconds since the Epoch using a formula that approximates the number of seconds between a specified time and the Epoch.
This formula takes account of the facts that all years that are evenly divisible by 4 are leap years, but years that are evenly divisible
by 100 are not leap years unless they are also evenly divisible by 400, in which case they are leap years. This value is not the same as
the actual number of seconds between the time and the Epoch, because of leap seconds and because system clocks are not required to be syn-
chronized to a standard reference. The intention is that the interpretation of seconds since the Epoch values be consistent; see
POSIX.1-2008 Rationale A.4.15 for further rationale.
