LPAR to Have 2 AS/400 O/S on One Machine?

Our sister company has an 8203-E4A installed with V6R1.  Since we're a software company having to support customers running V5R2, we have a separate machine running V5R2, but it's out of warranty and it'll be so expensive to upgrade it to V5R4.  Is it possible to create two LPARs on our sister company's machine with one running V6R1 and another running V5R4?

Also regarding LPAR's -- does it make the machine behave like two separate systems?  Is it possible to have one with system date in Pacific and another in Eastern Time, for example?

Thanks so much for your input.

Yes, you can run different supported versions of the OS is different partitions.  You can even create partitions running AIX and Linux.

Yes, each partition is a full virtual machine, with it's own independent OS, applications, libraries, system values, configuration, etc.

Yes, you can set time zones, languages, character sets, and any other setting to any valid value in each partition.

Here's the IBM spec sheet for the Power 520 (that's the 8203-E4A):  ftp://ftp.software.ibm.com/common/ssi/pm/sp/n/pod03001usen/POD03001USEN.PDF
The following OS's are supported on this particular hardware:

AIX V5.3 or later
IBM i V5R4 or later
SUSE Linux Enterprise Server 10 for POWER" (SLES10 SP1) or later;
Red Hat Enterprise Linux 4.5 for POWER (RHEL4.5) or later;
RHEL5.1 or later

Here's the IBM LPAR Redbook.  It was developed under V5R3, so a few things have changed, but it is still a great resource for understanding logical partitioning:
