as.duration(h_age) #> [1] "1167350400s (~36.99 years)"

Durations come with a bunch of convenient constructors:

dseconds(15) #> [1] "15s" dminutes(10) #> [1] "600s (~10 minutes)" dhours(c(12, 24)) #> [1] "43200s (~12 hours)" "86400s (~1 days)" ddays(0:5) #> [1] "0s" "86400s (~1 days)" #> [3] "172800s (~2 days)" "259200s (~3 days)" #> [5] "345600s (~4 days)" "432000s (~5 days)" dweeks(3) #> [1] "1814400s (~3 weeks)" dyears(1) #> [1] "31536000s (~52.14 weeks)"

Durations always record the time span in seconds. Larger units are created by converting minutes, hours, days, weeks, and years to seconds at the standard rate (60 seconds in a minute, 60 minutes in an hour, 24 hours in day, 7 days in a week, 365 days in a year).

You can add and multiply durations:
