# HG changeset patch # User Christian Limpach <Christian.Limpach@xxxxxxxxxxxxx> # Date 1173369092 0 # Node ID 345effaf2258f1059172023d542ff011468d702c # Parent 7e2f7e8b63d3013efc0e009bc16509daa011a3be [xen] Update the hvm rtc clock state if the domain's time offset is changed. The settimeoffset domctl had no effect on hvm domains since the offset was only read in rtc_init which is done when the domain is created.
