Dada una marca de tiempo T de Unix (en segundos) para un punto dado en el tiempo, la tarea es convertirlo a un formato legible por humanos (DD/MM/YYYY HH:MM:SS)
Ejemplo:
Entrada: T = 1595497956
Salida: 23/7/2020 9:52:36
Explicación: En tiempo unix T tiene 1595497956 segundos, por lo que hace un total de 50 años, 7 meses, 23 días y 9 horas, 52 minutos y 36 segundos.Entrada: T = 345234235
Salida: 12/9/1980 18:23:55
Acercarse:
- Convierta los segundos dados en días dividiéndolos por la cantidad de segundos en un día (86400) y almacene el segundo restante.
- Dado que contamos el número de días desde el 1 de enero de 1970. Por lo tanto, para calcular el año actual tenga en cuenta el concepto de años bisiestos. Comience en 1970. Si el año es un año bisiesto, reste 366 a los días; de lo contrario, reste 365. Aumente el año en 1.
- Repita el paso 2 hasta que los días sean menos de 365 (no puede constituir un año).
- Agregue 1 a los días restantes (días adicionales después de calcular el año) porque los días restantes nos darán días hasta el día anterior, y tenemos que incluir el día actual para el cálculo de FECHA y MES.
- Incremente el número de meses en 1 y siga restando el número de días del mes de los días adicionales (teniendo en cuenta que febrero tendrá 29 días en un año bisiesto y 28 en caso contrario).
- Repita los pasos 5 hasta que restar los días del mes de los días adicionales dé un resultado negativo.
- Si los días adicionales son más de cero, incremente el mes en 1.
- Ahora aproveche el tiempo extra del paso 1.
- Calcula las horas dividiendo el tiempo extra por 3600, los minutos dividiendo los segundos restantes por 60, y los segundos serán los segundos restantes.
A continuación se muestra la implementación del enfoque anterior:
