Setiap tahap dalam hierarki ini digelar <i>stratum</i> dan diberikan nombor lapisan bermula dengan 0 (sifar) di puncak. Tahap stratum mentakrifkan jaraknya dari jam rujukan dan wujud bagi menghalang kebergantungan siklik dalam hierarki. Adalah penting menyedari bahawa stratum bukanlah petunjuk kualiti atau keutuhan, adalah biasa mendapati sumber masa "stratum 3" yang berkualiti lebih tinggi berbanding sumber waktu "stratum 2". Pengtakrifan "stratum" juga berbeza dengan tanggapan lapisan jam yang digunakan dalam sistem telekomunikasi. </p> <dl><dt>Stratum 0</dt> <dd>Ini adalah peranti seperti jam atom (sesium, rubidium) , jam GPS atau jam radio yang lain. Peranti Stratum-0 secara tradisi tidak disambung kepada rangkaian; sebaliknya ia disambung tempatan kepada komputer(contohnya., melalui sambungan <a href="/wiki/RS-232" title="RS-232">RS-232</a> menggunakan isyarat Denyutan sesaat.</dd> <dt>Stratum 1</dt> <dd>Ini merupakan komputer disambungkan kepada peranti Stratum 0.

Komputer ini juga dikenali sebagai pelayan masa.</dd> <dt>Stratum 2</dt> <dd>Ini merupakan komputer yang menghantar permohonan NTP kepada pelayan Stratum 1. Biasanya komputer Stratum 2 akan merujuk kepada beberapa pelayan Stratum 1 dan menggunakan algoritma NTP untuk mendapatkan contoh data terbaik, meninggalkan sebarang pelayan Stratum 1 yang jelas silap. Komputer Stratum 2 akan will setara dengan komputer Stratum 2 lain bagi memberikan masa yang lebih stabil dan tahan bagi kesemua peranti dalam kumpulan setara. Komputer Stratum 2 biasanya bertindak sebagai pelayan bagi permohonan Stratum 3 NTP.</dd> <dt>Stratum 3</dt> <dd>Komputer ini menggunakan fungsi NTP yang sama bagi setara dan contoh data seperti Stratum 2, dan diri mereka juga mampu bertindak sebagai pelayan bagi lapisan lebih rendah.
