Revision 1.31, Sat Dec 23 20:04:23 2017 UTC (6 years, 5 months ago) by cheloha
Branch: MAIN
CVS Tags: OPENBSD_6_7_BASE, OPENBSD_6_7, OPENBSD_6_6_BASE, OPENBSD_6_6, OPENBSD_6_5_BASE, OPENBSD_6_5, OPENBSD_6_4_BASE, OPENBSD_6_4, OPENBSD_6_3_BASE, OPENBSD_6_3
Changes since 1.30: +10 -8 lines

Use the monotonic clock for logging progress in cdio(1) and ftp(1).

Keeps the progress log from blipping or stalling if, e.g., the
system time is changed in the midst of a rip or a transfer.
