Module palmrs_database::time

PalmTimestamp type & conversion methods

Palm OS has two epochs used for storing time - the “old Palm epoch” (seconds since 1904-01-01 00:00:00), and the standard UNIX epoch (seconds since 1970-01-01 00:00:00). If the “old Palm epoch” is used for storing the time, it is stored as an unsigned 32-bit integer, but if the UNIX epoch is used, it is stored as a signed 32-bit integer.

This module provides the PalmTimestamp helper type, which can be used within larger data structures to provide automatic timestamp format conversion. This module also provides various helper methods for timestamp format detection, and conversion between the timestamp formats.

Structs

• PalmTimestamp
  Type representing a Palm OS timestamp

Constants

• SECONDS_BETWEEN_PALM_EPOCHS
  The number of seconds between the two Palm OS timestamp epochs.

Functions

• is_palm_epoch
  Check if the given timestamp is using the “old Palm epoch”
• palm_ts_to_unix_ts
  Convert an “old Palm epoch” timestamp to a UNIX epoch timestamp
• unix_ts_to_palm_ts
  Convert a UNIX epoch timestamp to an “old Palm epoch” timestamp
