libfaketime intercepts various system calls which programs use to
|
||
|
|
retrieve the current date and time. It can then report faked dates and times
|
||
|
|
(as specified by you, the user) to these programs. This means you can modify
|
||
|
|
the system time a program sees without having to change the time system-wide.
|
||
|
|
|
||
|
|
libfaketime allows you to specify both absolute dates (e.g., 01/01/2004) and
|
||
|
|
relative dates (e.g., 10 days ago).
|
||
|
|
|
||
|
|
libfaketime might be used for various purposes, for example
|
||
|
|
|
||
|
|
- running legacy software with y2k bugs
|
||
|
|
- testing software for year-2038 compliance
|
||
|
|
- debugging time-related issues, such as expired SSL certificates
|
||
|
|
- running software which ceases to run outside a certain timeframe
|
||
|
|
- using different system-wide date and time settings, e.g., on OpenVZ-
|
||
|
|
based virtual machines running on the same host
|
||
|
|
- deterministic build processes.
