20230101T000000Z

20230101T000000Z denotes a precise moment in time encoded in a compact ISO 8601–like format. The 'T' separates date and time, and the trailing 'Z' indicates that the time is in Coordinated Universal Time (UTC). The date portion reads 2023 for the year, 01 for January, and 01 for the day, with the time at 00:00:00.

This form uses a compact, non-delimited date part (YYYYMMDD) followed by the letter T, the time in HHMMSS, and the Z suffix. While similar to ISO 8601, which normally uses separators like 2023-01-01T00:00:00Z, many data systems adopt the compact variant for compactness or legacy reasons.

As a representation of a universal moment, it is widely used in software logging, data interchange, version control, and scheduling metadata. Converting to other time zones changes both the clock time and possibly the calendar day. For example, in UTC−05:00 (Eastern Standard Time), 20230101T000000Z corresponds to 2022-12-31T19:00:00-05:00.

In terms of standards, the string aligns with RFC 3339 and ISO 8601 conventions for representing instants, though some systems may enforce stricter delimiter requirements or different offset formats. Users should ensure that parsers interpret the Z suffix as UTC to avoid misinterpretation when displaying local times.
