`period_to_seconds` considers that a year is equal 365 days while `seconds_to_period` considers that a year is equal to 365.25 days. Therefore: ``` r > seconds_to_period(period_to_seconds(years(2))) [1] "1y 0m 364d 18H 0M 0S" ```
period_to_secondsconsiders that a year is equal 365 days whileseconds_to_periodconsiders that a year is equal to 365.25 days.Therefore:
