Almost users will not have to +worry about these settings, and can ignore the following explanation. + +In almost all situations, \fIlatexmk\fR does not need to use the time +stamps of the files it works with. However, there are a couple of +situations when it needs to know whether a certain file was created in +the current run of a program (e.g., \fI(pdf)latex\fR) or is a leftover +file from a previous run. It does this by comparing the modification +time of the file with the system time just before the program was +started. If the modification time is earlier than when the program was +started, the file is a leftover file, which \fIlatexmk\fR treats as if +it were not created. If the filetime is at least the program start +time, then it can be assumed that the file was created in the current +run. + +Unfortunately, this test can fail if the file is on a remote system, +since its system time is not necessarily synchronized with that of the +local system; the timestamps on the remote files are set by the remote +system, not the local system. Generally, modern operating systems +regularly synchronize their time with a server, so the +non-synchronization is mostly small (a second or so, or a few +seconds). But even a small difference can mess up \fIlatexmk\fR's +test. + +\fILatexmk\fR measures the time difference between the time on the two +systems and compensates for this. But the measurement (in a +system-independent way) is only accurate to a second or two. So +\fIlatexmk\fR allows for a threshold on the difference between file +and system time before it concludes that a file is a leftover file +from a previous run. The configuration variable +\fI$filetime_causality_theshhold\fR, which in units of seconds, +specifies this threshold. Luckily high precision is not needed. The +previous run is normally the previous run in a human run-edit-run +cycle, and is at least many seconds back.
