#### 15.5.3 File Time

As stated above, file time is operating-system dependent. As of this writing, two formats are used. For unix and Windows systems, file time is the number of seconds since midnight January 1, 1970 UTC (the standard unix time convention).

The following procedures generate their results in file-time format:

    file-access-time
    file-access-time-direct
    file-access-time-indirect
    file-modification-time
    file-modification-time-direct
    file-modification-time-indirect
    file-attributes/access-time
    file-attributes/modification-time
    file-attributes/change-time

Additionally, `set-file-times!` accepts its time arguments in file-time format.
