Como adicionar tempo no meu script

Eu tenho 3 scripts para construir o OpenWrt, mas não consigo configurá-lo para ter tempo no final. Aqui está o que o script dá e o script. openwrt-snapshot-r22256+29-14334c222e-ipq806x-generic-linksys_ea8500-sysupgrade.bin

Mas eu quero esse tipo de descrição com o tempo: openwrt-snapshot-r22256+29-14334c222e-20230310-ipq806x-generic-linksys_ea8500-sysupgrade.bin
