From Telemetry

(Telemetry) routine periods

multi sub periods( --> Seq)
multi sub periods(@s --> Seq)

The periods subroutine processes an array of Telemetry objects and generates a Seq of Telemetry::Period objects out of that. It is exported by default.

.<cpu wallclock>.say for periods(@t);

# OUTPUT:
# ====================
# (164 / 160)
# (23 / 21)
# (17 / 17)
# (15 / 16)
# (29 / 28)

If no array is specified, it will use the internal array of snap without parameters and will reset that array upon completion (so that new snaps can be added again).

use Telemetry;
for ^5 {
    snap;
    LAST snap;
}
say .<cpu wallclock>.join(" / ") for periods;

# OUTPUT:
# ====================
# 172 / 168
# 24 / 21
# 17 / 18
# 17 / 16
# 27 / 27

If only one snap was done, another snap will be done to create at least one Telemetry::Period object.
