Caveats

Section titled “Caveats”

Time codes before the year 1902 or past the end of 2037 are limited due to the size of LSL’s 32-bit integers. As of writing (2024) this is just 14 years away now and any scripts relying on this function may have logical errors.

Helper Functions

Section titled “Helper Functions”

The following helper functions can be useful when working with Unix timestamps:

  • Unix2StampLst - Converts Unix Time stamp to a list. Example: 1234567890 to [2009, 2, 13, 23, 31, 30]
  • Stamp2UnixInt - Converts date to Unix Time stamp. Example: [2009, 2, 13, 23, 31, 30] to 1234567890
  • uuLinuxTime - Converts date to Unix Time stamp (from Linux kernel’s sources)
  • Unix2WeekdayStr - Gets the weekday from a Unix Time stamp. Example: “Friday” from 1234567890
  • Unix2PST_PDT - Converts Unix Time stamp to an SLT date/time string with PST or PDT indication as appropriate
  • Unix2GMTorBST - Converts Unix Time stamp to a UK date/time string with GMT or BST indication as appropriate
