# Timestamps

Timestamp fields are based on a subset of ISO 8601. When being as precise as possible the format of a time string is:

> yyyy-MM-ddTHH:mm:ss

> yyyy is the year

> MM is the month

> dd is the day

> HH is the hour (0 to 23)

> mm is the minutes

> ss is the seconds

> -, T and : are literal characters

The precision may be reduced by removing as many time indicators as wanted.

The following are all valid timestamps:

> yyyy

> yyyy-MM

> yyyy-MM-dd

> yyyy-MM-ddTHH

> yyyy-MM-ddTHH:mm

> yyyy-MM-ddTHH:mm:ss

Yate does not enforce the formatting of timestamps while editing, however the Log>Validation errors will identify all malformed timestamp fields. The most common usage of timestamps is in the Year field.
