Caution

This data pack is highly dependent on the internal implementation details of Minecraft and may not work in future versions.

Calculates the current value of the JVM's high-resolution time source in milliseconds ((System.nanoTime() / 1000000L) & 0x0000ffffffffffff).

Example usage

# Initialize once.
function get_millis:init

# Get the millis. The execution position must be loaded to place the template.
execute positioned 0 0 0 run function get_millis:

# The result is split into high 32 bits (#millis[63:32] get_millis)
# and low 32 bits (#millis[31:00] get_millis).
