Description
i1 : currentTime()
o1 = 1594132574

We can compute, roughly, how many years ago the epoch began as follows.
i2 : currentTime() /( (365 + 97./400) * 24 * 60 * 60 )
o2 = 50.5160502826762
o2 : RR (of precision 53)

We can also compute how many months account for the fractional part of that number.
i3 : 12 * (oo  floor oo)
o3 = 6.19260339211471
o3 : RR (of precision 53)

Compare that to the current date, available from a standard Unix command.
i4 : run "date"
Tue Jul 7 09:36:14 CDT 2020
o4 = 0
