Java GUI app to convert dates and epoch time (in milliseconds) between each other.
Dates use the following format (Timezones are not accepted). Note that dates can be partially completed and the missing elements will be assumed as zero. Entering only numbers will assume the input as being an epoch time
Full date string
yyyy-MM-dd HH:mm:ss,SSS
Partial date strings
yyyy-MM-dd HH:mm
yyyy-MM-dd
yyyy-
Anything less is assumed as an epoch time
Date era (BC, AD) can be set to BC by clicking the checkbox marked 'BC'. Unchecked means AD. This only applies when entering a date string, if entering an epoch time the era will be set automatically.
