This adds support to unshare for time namespaces. With the newly added options '-t, --time' and '--monotonic' and '--boottime' it is now possible to change CLOCK_MONOTONIC and CLOCK_BOOTTIME in a new time namespace. The time namespace has been merged in kernel version 5.6 and an easy way to test it is using CLOCK_BOOTTIME and the uptime command: # uptime 11:08:26 up 20:28, 1 user, load average: 0.00, 0.00, 0.00 # ./unshare --fork --time --boottime 100000000 uptime 11:08:29 up 1158 days, 6:15, 1 user, load average: 0.00, 0.00, 0.00 Signed-off-by: Adrian Reber <areber@redhat.com>
