Subject: Monotonic clock cannot jump backwards.
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=c27c731b9f77c1b1c99f3bde737be53996809fcb;p=st.git

Monotonic clock cannot jump backwards.

The check was introduced back when st used gettimeofday.
The condition is also modified to increment the accuaracy of the
calculation.
