.SH "Detailed Description"
.PP 
ISO C++ 2014 namespace for suffixes for duration literals\&.
.PP
These suffixes can be used to create \fCchrono::duration\fP values with tick periods of hours, minutes, seconds, milliseconds, microseconds or nanoseconds\&. For example, \fCstd::chrono::seconds(5)\fP can be written as \fC5s\fP after making the suffix visible in the current scope\&. The suffixes can be made visible by a using-directive or using-declaration such as:
.IP "\(bu" 2
\fCusing namespace std::chrono_literals;\fP
.IP "\(bu" 2
\fCusing namespace std::literals;\fP
.IP "\(bu" 2
\fCusing namespace std::chrono;\fP
.IP "\(bu" 2
\fCusing namespace std;\fP
.IP "\(bu" 2
\fCusing std::chrono_literals::operator''s;\fP
.PP
.PP
The result of these suffixes on an integer literal is one of the standard typedefs such as \fCstd::chrono::hours\fP\&. The result on a floating-point literal is a duration type with the specified tick period and an unspecified floating-point representation, for example \fC1\&.5e2ms\fP might be equivalent to \fCchrono::duration<long double, chrono::milli>(1\&.5e2)\fP\&.
