Analysis of Timezone and Millisecond Handling in Gson Date Format Parsing
This article delves into the internal mechanisms of the Gson library when parsing JSON date strings, focusing on the impact of millisecond sections and timezone indicator 'Z' when using the DateFormat pattern "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'".
