1515612110270

1515612110270 is a numeric timestamp expressed in milliseconds since the Unix epoch (00:00:00 UTC on 1 January 1970). When interpreted as UTC time, it corresponds to 2018-01-10T19:21:50.270Z.

Such millisecond-based timestamps are commonly used in computing to record exact moments in time, especially in programming environments that operate with millisecond precision, like JavaScript. They enable straightforward time calculations, such as determining the duration between events or ordering events chronologically.

Usage considerations include the need to interpret the value as milliseconds rather than seconds, which is a common source of errors when exchanging time data between systems. The value 1515612110270 is well within the precise representational range of 64-bit and 53-bit floating-point numbers used in most modern programming languages, including JavaScript. However, some languages or systems that store timestamps as 32-bit integers may overflow or lose precision, so appropriate data types should be chosen.

Conversions to other formats are straightforward: the ISO 8601 representation is 2018-01-10T19:21:50.270Z, and local time equivalents vary by time zone. When displaying to users, including time zone information helps prevent confusion.
