Detailed Description

Helper class that allows to convert time stamps as defined in LCEvent::getTimeStamp() ( ns since 1.1.1970 00:00:00 UTC) to ordinary date and time and vice versa.

Dates and times are in UTC/GMT by default.
Negative time stamps are not supported and mapped to 0LL and 1.1.1970 00:00:00 UTC respectively.
