PINT AE validation rule for UAE e-invoices
Every time on the invoice must be in the format hh:mm:ss. Fractions of a second and a time zone are optional.
Write each time as hh:mm:ss.
The official wording of this rule is in the PINT AE specification published by OpenPeppol.
Alya Books builds the invoice XML so this holds; the official rule files confirm it on our sample documents.
يجب أن يكون كل وقت في الفاتورة بالصيغة hh:mm:ss. وأجزاء الثانية والمنطقة الزمنية اختيارية.
اكتب كل وقت بالصيغة hh:mm:ss.
See this rule in the interactive reference, or pre-check an invoice file.
