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.

Is there a method to inject events into the SEL, to basically restore from a previously saved raw dump?

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 ipmitool sel clear Clearing SEL.
