std::chrono::file_clock
Member functions
(optional*)
(optional*)
Time point I/O
Defined in header
<chrono>
using file_clock = /* see below */;
(since C++20)
std::chrono::file_clock is an alias for the clock used for std::filesystem::file_time_type . Its epoch is unspecified.
file_clock meets the TrivialClock requirements.
Time point family
Defined in namespace
std::chronotemplate<class Duration>
using file_time = std::chrono::time_point <std::chrono::file_clock, Duration>;
(since C++20)
using file_time = std::chrono::time_point <std::chrono::file_clock, Duration>;
[edit] Member types
Member type

rep
signed arithmetic type representing the number of ticks in the clock's duration
period
a std::ratio type representing the tick period of the clock, in seconds
duration
std::chrono::duration <rep, period>, capable of representing negative durations
time_point
std::chrono::time_point <std::chrono::file_clock>
