x1 is the time-duration/interval/period/[elapsed time] from time/event x2 to time/event x3.

Also age/elapsed time (= niltei). See also cacra, cedra, citsi, ranji, tcika, junla, renvi.

In notes:

cacra
x1 is x2 hours in duration (default is 1 hour) by standard x3.
cedra
x1 is an era/epoch/age characterized by x2 (event/property/interval/idea).
citsi
x1 is a season/is seasonal [cyclical interval], defined by interval/property x2, of year(s) x3.
junla
x1 is clock/watch/timer measuring time units x2 to precision x3 with timing mechanism/method x4.
ranji
x1 (event/state) continues/persists over interval x2; x1 (property - ka) is continuous over x2.
renvi
x1 survives/endures/undergoes/abides/lasts/persists through x2 for interval/duration x3.
tcika
x1 [hours, minutes, seconds] is the time/hour of state/event x2 on day x3 at location x4.
cabyku'e
k1=c1 ranges through time/has duration k2=c2.
caljvetei
c1=t1 is space-time occupied by c2.
cistcika
t1 (hours, minutes, seconds) is the daylight saving time of state/event t2 on day t3 at location t4=c3.
faurtei
f1 is an event that has time/temporal duration t1 ranging from starting time/event t2 to ending time/event t3.
kanjunla
j1=k1 is a watch (portable timepiece) measuring time units j2 to precision j3 with timing mechanism j4.
lirmau
x1 is earlier than x2 by amount of time x3.
temfesti
f1 is a ruin that has decayed from time/event t2 to time/event t3
temli'u
x1=l1 is a time traveller travelling over time interval x2=l2=t1 from x3=t2 to x4=t3 with time machine/time travel device x5=l3
temsepcau
c1=s1 is immediately next to s2 in time.
zatra'i
r1=z1 exists over interval r2.
ditcu
x1 is the time-duration/interval/period/[elapsed time] of event x2.
