Hi Holger and Zdenek,
Thank you both for the guidance! I've pulled
ipmi-intelligent-platform-mgt-interface-spec-2nd-gen-v2-0-spec-update.pdf for
future reference.
Cheers,
Brad

event
Hi Brad,
Short answer: not possible
Long answer (quote from the IPMI Spec. Section 31.6 Add SEL Entry Command):
…
Records are added on after the last record in the SEL. The SEL Device adds the
timestamp according to the SEL Record Type (see 31.6.1, SEL Record Type Ranges,
following) when it creates the record. Thus, in some cases the timestamp bytes
in the record data are ignored. However, ‘dummy’ timestamp bytes must still be
present in the data.

Changing this up a little, reading the man page one might think 'sel readraw
file' would inject entries into the SEL with time stamps intact but that is not
the case. Is there a method to inject events into the SEL, to basically
restore from a previously saved raw dump?
Thank you,
Brad

Subject: [Ipmitool-devel] Preserving SEL date/time stamps across a clear event
Hi,
The objective here is to save the SEL to a file before an event that clears it,
then repopulate it from the saved file then continue logging events from that
point on with appropriate date/time stamps. The problem (perceived) is that
ipmitool sel add file resets previously recorded date/time stamps to the
current date and time effectively debasing the integrity of the log.
ipmitool version 1.8.15
Steps to reproduce:
ipmitool sel list
a | 02/29/2016 | 22:06:33 | Event Logging Disabled #0x8c | Log area
reset/cleared | Asserted
b | 02/29/2016 | 22:19:42 | Other Units-based Sensor #0xa0 | State Asserted
| Asserted
c | 02/29/2016 | 22:19:43 | System Boot Initiated #0x87 | System Restart |
Asserted
d | 02/29/2016 | 22:20:06 | System Event #0x8e | Timestamp Clock Sync |
Asserted
e | 02/29/2016 | 22:20:08 | System Event #0x8e | Timestamp Clock Sync |
Asserted
f | 02/29/2016 | 22:20:51 | System Event #0x8f | OEM System boot event |
Asserted
10 | 02/29/2016 | 22:21:01 | System ACPI Power State #0x88 | S0/G0: working |
Asserted

This smells like a bug to me but I wanted to check with the experts before I
proceed.
Thank you,
Brad
