Function `core.time.convert`

Generic way of converting between two time units. Conversions to smaller units use truncating division. Years and months can be converted to each other, small units can be converted to each other, but years and months cannot be converted to or from smaller units (due to the varying number of days in a month or year).

				  long value
				

				) pure nothrow @nogc @safe
				

				if ((from == "weeks" || from == "days" || from == "hours" || from == "minutes" || from == "seconds" || from == "msecs" || from == "usecs" || from == "hnsecs" || from == "nsecs") && (to == "weeks" || to == "days" || to == "hours" || to == "minutes" || to == "seconds" || to == "msecs" || to == "usecs" || to == "hnsecs" || to == "nsecs") || (from == "years" || from == "months") && (to == "years" || to == "months"));

Parameters

Name	Description
from	The units of time to convert from.
to	The units of time to convert to.
value	The value to convert.

Example

writeln(convert!("years", "months")(1)); // 12
writeln(convert!("months", "years")(12)); // 1

writeln(convert!("weeks", "days")(1)); // 7
writeln(convert!("hours", "seconds")(1)); // 3600
writeln(convert!("seconds", "days")(1)); // 0
writeln(convert!("seconds", "days")(86_400)); // 1

writeln(convert!("nsecs", "nsecs")(1)); // 1
writeln(convert!("nsecs", "hnsecs")(1)); // 0
writeln(convert!("hnsecs", "nsecs")(1)); // 100
writeln(convert!("nsecs", "seconds")(1)); // 0
writeln(convert!("seconds", "nsecs")(1)); // 1_000_000_000
