92 . | |
93 .Nm | |
94 does not make any math on the input: if the timestamps are not at regular | |
95 interval, ploot will still print one output line every 4 lines read, | |
96 regardless of the time interval. | |
97 . | |
98 .Pp | |
99 However, the timestamp printed on the left is always exact. |
