[Xen-devel] [PATCH v3] Change timestamps representation for keyhandlers

[Andrii Anisov <andrii.anisov@xxxxxxxxx>]

From: Andrii Anisov <andrii_anisov@xxxxxxxx>

For different keyhandlers, replace a hex with delimiter representation
of time to PRI_stime which is decimal ns currently.

Signed-off-by: Andrii Anisov <andrii_anisov@xxxxxxxx>

Changes in v3:
    - patch a missed dump_domains() keyhandler

Changes in v2:
    - Time representation change propagated to all keyhandlers as agreed here
